This is a very general question as most of the coders are working still on Turbo C++ IDE. So here is a simple  solution to make your Turbo C++ Program compatible for CodeBlocks IDE. Let's Consider the following Simple Code of Insertion Sort  :- So, In the above C++ code,  In order to make this compatible to CodeBlocks, we have to follow these 6 simple steps :- 1.  Replace the header file - #include<iostream.h> with - #include<iostream> 2. Replace the next header file - #include<conio.h> with - using namespace std; 3. Replace the 3rd line - void main() with int main() 4. Remove the 5th line - clrscr(); 5. Replace the 2nd last line - getch(); with - return 0; 6. That's all Enjoy The resultant code will be like this - So, In this way we can run most of the  C++ codes written in Turbo C++ in CodeBlocks IDE.

Hello Guys.... This is my second post and in this i am going to talk about Arrays in Java Programming Language. So let's get started:- 1-D Array There are two ways of declaring 1-D array in java :- 1st Method (without using the new keyword) :- Consider this code :-  When we  run this code in a file named array.java we get the output as follows :- Months -  1 2 3 4 5 6 7 8 9 10 11 12 2nd Method (using the new keyword) :- Consider this code :- When we run this code in a file named array.java we get the output as follows :- Rahul Malhotra is a coder   2-D Array    We can declare the 2-D array in java also by two methods :- 1st Method (using the new keyword) :- The declaration of the 2-D array is the same by the two methods that we just discussed in the 1-D array. The main feature that Java provides in the 2-D array is that, out of the two attributes, one attribute is fixed and other can vary.... Let's learn wi

Hello Guys.... This is my first post and in this i am going to talk about some of the important basics and concepts of Java Programming Language which are generally ignored by most of us... I hope that after reading this post many basic concepts regarding java will be cleared to you.So let's get started:-   1. Automatic Type Promotion  Consider this code :-  public class promotion {     public static void main(String args[])     {         byte a=10;         byte b=2;         byte c=a*b;         System.out.println("Result of 10x2 = "+c);     } } When we  run this code in a file named promotion.java we get the error as follows :- Exception in thread "main" java.lang.Error: Unresolved compilation problem:     Type mismatch: cannot convert from int to byte     at promotion.main(promotion.java:7) So why do we get this error ???? as we know that the range of the byte is 256 and the multiplication of  'a' and 'b' is 20 whi
