C++ Control Structures Part 3 : Loop Structure | for, while, do while | while & do while Difference

                  In this post, we will see C++ Control Structures Part 3 : Loop Structure | for, while, do while | while & do while Difference 

Program Code: (loopstructure1.cpp)

#include<iostream>

using namespace std;

int main()

{

    int i;

    for(i=0;i<5;i++)

    {

        cout<<"Square of "<<i<<"="<<i*i<<endl;

    }

    //infinite loop

    /*

    for(;;)

    {

    cout<<"Hello World"<<endl;

    }

    */

}

Program Code: (loopstructure2.cpp)

#include<iostream>

using namespace std;

int main()

{

    int i=0;

    while(i<5)

    {

        cout<<"Square of "<<i<<"="<<i*i<<endl;

        i++;

    }

    //infinite loop

    /*

    while(true)

    {

        cout<<"Square of "<<i<<"="<<i*i<<endl;

        i++;

    }

    */

}

Program Code: (loopstructure3.cpp)

#include<iostream>

using namespace std;

int main()

{

int i=0;

do

{

    cout<<"Square of "<<i<<"="<<i*i<<endl;

    i++;

} while (i<5);

}
