How we can use simple for loop in c++ code

For loop is also use for repetition. In for loop we initialize the object, use condition and increment operator in one small brackets with the keyword for. You can see the code and understand the use of for loop in right way.

Code:

#include <iostream>

using namespace std;

int main()

{

                int i;

                for(i=0;i<=20;i++)

                {

                                cout<<i<<endl;

                }

               

}

Output:
