10 Programming Languages Must should be Learn Right Now
Java
Java is a class-based, object-oriented programming language developed by Sun Microsystems in the 1990s. It’s one of the most in-demand programming languages, a standard for enterprise software, web-based content, games and mobile apps, as well as the Android operating system. Java is designed to work across multiple software platforms, meaning a program written on Mac OS X, for example, could also run on Windows.

2. Python
Python is a high-level, server-side scripting language for websites and mobile apps. It’s considered a fairly easy language for beginners due to its readability and compact syntax, meaning developers can use fewer lines of code to express a concept than they would in other languages. It powers the web apps for Instagram, Pinterest and Rdio through its associated web framework, Django, and is used by Google, Yahoo! and NASA.
3.C Language
Where to learn it: Learn-C, Introduction To Programming, Lynda.com, CProgramming.com,Learn C The Hard Way.
4. C++
Pronounced “C-sharp,” C# is a multi-paradigm language developed by Microsoft as part of its .NET initiative. Combining principles from C and C++, C# is a general-purpose language used to develop software for Microsoft and Windows platforms.
5. Objective-C
Objective-C is a general-purpose, object-oriented programming language used by the Apple operating system. It powers Apple’s OS X and iOS, as well as its APIs, and can be used to create iPhone apps, which has generated a huge demand for this once-outmoded programming language.
6. PHP
What it is: PHP (Hypertext Processor) is a free, server-side scripting language designed for dynamic websites and app development. It can be directly embedded into an HTML source document rather than an external file, which has made it a popular programming language for web developers. PHP powers more than 200 million websites, including WordPress, Digg andFacebook.
7.JavaScript
JavaScript is a client and server-side scripting language developed by Netscape that derives much of its syntax from C. It can be used across multiple web browsers and is considered essential for developing interactive or animated web functions. It is also used in game development and writing desktop applications. JavaScript interpreters are embedded in Google’s Chrome extensions, Apple’s Safari extensions, Adobe Acrobat and Reader, and Adobe’s Creative Suite.
8.SQL
Structured Query Language (SQL) is a special-purpose language for managing data in relational database management systems. It is most commonly used for its “Query” function, which searches informational databases. SQL was standardized by the American National Standards Institute (ANSI) and the International Organization for Standardization (ISO) in the 1980s.

tic tac toe
To test your skills against a modern foe, search “tic tac toe”.
On 1975, Students at M.I.T build a computer almost entirely out of TinkerToys, that’s able to play tic–tac perfectly.

Competitive Programming
Programmers have a life, though mostly bound to their computers.
Competitive programming is a popular event for programmers and students alike that tests and sharpens the competitor’s knowledge and skill on mathematics and computer programming, and introduces aspiring computer performer or computer master / computer geeks to the world.
Competitive programming is similar to quiz contests. Here a team or individual is given a number of mathematical and logical problems to solve using any programming language allowed by the host. The competition can span from just a few hours to even months. The categories of problems cover many mathematical concepts like data structures, graphs, number theory, dynamic programming, string processing, algebra, geometry and much more. The competitions take place online – on both local and global networks.

don’t learn to code for computer software
Engineering and Programming are important skills.
There’s an idea that’s been gaining ground in the tech community lately: Everyone should learn to code.
ocusing on coding inflates the importance of finding the “right” method to solve a problem rather than the importance of understanding the problem.
Programmers Never Die…!!!
Programmers Never Die…!!!
But, Not In a day, or a Month, or an Instantly
You shouldn’t become an Expert Programmer, Software Engineer.
Absolutely, To become an Expertise Software Engineer through great Practices, Study.
Stack
I think that everyone knows a few or less info about ” Stack ” . but I like to post a simple idea about Stack that can help you.
A Stack stores data using first-in, last – out ordering. Absolutely, a stack is likely a stack of plates on a table – that the first plate put down on the table and the last palte to be used. Stacks are controlled through two operations called as push and pop.
JAVA :: Think Object Oriented Programming
Object Oriented Programming is at the core of JAVA…
In fact, all Java programs are Object Oriented and all computer programs consist of two elements : CODE and DATA. Why Object Oriented Programming – because Object Oriented Programming organizes a program around its data (that is Object) and a set of well-defined interfaces. Java programs are a collection of whitespace, Identifiers, Comments, Literals, Operators.
Java is a free form of language. This means that you do not need to follow any special indentication rules. A programmer could have been written all on one in line or in any other strange way felt like typing it. In Java whitespace is a space, tab, or newline.
Identifiers are used for class names, method names, and variable names. An identifier may be any descriptive sequence of upper case (A, B, C…) & lowercase (a,b,c…) letters, numbers (0,1,2,..), or underscore (_), and dollar sign characters.
Java is a case-sensitive, So VALUE is a different identifier than Value.
Major Three Principle of OOP
All Object oriented Programing has contained three major principle rules.
Python Environment :: Python Programming
Start up writing the Python programs, let’s understand how to set up our Python environment.

Programming Basic|Startup
For good programming, we should require average basic knowledge on a C or C++. Later we have need to
In our country, now sequentially increased programming fair and lots of teenager, youth was participating in the programming fair. A few renowned programmers told that try to gather knowledge on programming concept by practice on programming, coding.
But don’t forget that most need basic knowledge on BOOLEAN ALGEBRAIC Functions and NUMBER System for doing good programming. Absolutely, that is the first condition to be a good programmer. You must have needed to know sufficient idea about this Boolean algebraic function and number system, because in the world, both of those using in c/c++, Java, vb.net, python or after all programming language. Because, computer, server computing, networking and after all electronic devices perform work with this 0 & 1.
Difference between # include in C/C++ and import in Java
*** Difference between # include in C/C++ and import in Java ***
– # include makes the compiler to copy header file code into the C/C++ program.
– It increase the program size, unnecessary wastage of memory and process time.
– import statement makes JVM to go to the java library and execute the code there and finally substitute the result into java program.
– JVM physically will not copy any code.
– import is efficient than # include
Happy Coding!!
Greedy Algorithm
Greedy Algorithm?
A greedy algorithm is a mathematical process that recursively constructs a set of objects from the smallest possible constituent parts. Recursion is an approach to problem solving in which the solution to a particular problem depends on solutions to smaller instances of the same problem.
Greedy algorithms look for simple, easy-to-implement solutions to complex, multi-step problems by deciding which next step will provide the most obvious benefit. Such algorithms are called greedy because while the optimal solution to each smaller instance will provide an immediate output, the algorithm doesn’t consider the larger problem as a whole. Once a decision has been made, it is never reconsidered.
The advantage to using a greedy algorithm is that solutions to smaller instances of the problem can be straightforward and easy to understand. The disadvantage is that it is entirely possible that the most optimal short-term solutions may lead to the worst long-term outcome.
Greedy algorithms are often used in ad hoc mobile networking to efficiently route packets with the fewest number of hops and the shortest delay possible. They are also used in machine learning, business intelligence (BI), artificial intelligence (AI) and programming.
Advantages & Disadvantages|C Language
Advantages of C Language
1. C language is a building block for many other currently known languages.C language has variety of data types and powerful operators. Due to this, programs written in C language are efficient, fast and easy to understand.
2. C is highly portable language. This means that C programs written for one computer can easily run on another computer without any change or by doing a little change.
3. There are only 32 keywords in ANSI C and its strength lies in its built-in functions. Several standard functions are available which can be used for developing programs.
4. Another important advantage of C is its ability to extend itself. A C program is basically a collection of functions that are supported by the C library this makes us easier to add our own functions to C library. Due to the availability of large number of functions, the programming task becomes simple.
5. C language is a structured programming language. This makes user to think of a problem in terms of function modules or blocks. Collection of these modules makes a complete program. This modular structure makes program debugging, testing and maintenance easier.
Disadvantages of C Language
1. C does not have concept of OOPs, that’s why C++ is developed.
2. There is no runtime checking in C language.
3. There is no strict type checking. For example, we can pass an integer value.
4. for the floating data type.
5. C doesn’t have the concept of namespace.
6. C doesn’t have the concept of constructor or destructor.
Abstract Class |
What is an Abstract Class
An abstract class is that class which is not used to create objects. – It is designed to act as a base class for other derived classes.
An example is shown below :
class student { . . . . . . . . . . }; class marks: public student { . . . . . . . . . . }; int main() { marks m; . . . . . . . . . . return 0; }
Stack Implementation : Operations In C

Platform Independent Programming Languages|PIPL
Actually, almost any language can be platform independent. It’s the distributable code that usually isn’t. Java code runs in a JVM. The JVM is platform specific, but theoretically Java programs will run on a JVM regardless of what OS it’s installed on.
Basically, any interpreted language should run on a system the successfully implements the interpreter. No one is 100% successful at this, however; no even Java. An executable is compiled for a specific OS. However, the source code can be completely portable. There are thousands of C and C++ programs that are said to be “cross platform” meaning they can be successfully compiled on different platforms without much pain. To clarify, not all languages use an interpreter.
A computer program, any program, executes within the context of some machine. The machine itself; CPU, memory, graphics card, etc, has a set of instructions it will run. These instructions are called machine code. Some, formerly most, programming languages are compiled into machine code. This results in a executable binary that runs directly against the machine itself. The result may be called compiled code and getting from source to binary is called compiling. Though sometimes as distinction is made between compiling and linking.
Java calls the process of going from source files (.java) to .class files compiling. However, the result can’t run on it’s own. The result is a preprocessed set of instructions ( p-code ) that the JVM ( interpretor ) runs. JVM stands for Java “Virtual Machine,”, the idea being that .class files are machine code inside the the VM. It’s a cute, if confusing, way for Java to obfuscate it’s interpreted nature. Because of the need for a middleman, the interpretor, interpreted languages are generally views as slower than their directly executable counter parts. However, the line can be blurry, depending how where the interpreting is happening. In some environments, the Operating System itself acts an interpretor for nearly everything executed.
A “scripting” language is usually interpreted, with an executable program reading the script and executing the instructions.
