I recommend to download : Dev C++
This application is used to program in C and C++
Write down the program down below on a new source file , to do that click on File , New , Source File
When you are done with writing the program , press on execute then compile & run , to compile the written code.
INPUT :
#include <iostream>
using namespace std;
int main()
