    /*Loops in C++:
    There are three types of loops in C++:
        1. For loop
        2. While Loop
        3. do-While Loop
    */

    /*For loop in C++*/
    int i=1;
    cout<<i;
    i++;

    Syntax for for loop
    for(initialization; condition; updation)
    {
        loop body(C++ code);
    }

    for (int i = 1; i <= 40; i++)
    {
        /* code */
        cout<<i<<endl;
    }

    Example of infinite for loop
    for (int i = 1; 34 <= 40; i++)
    {
        /* code */
        cout<<i<<endl;
    }

    /*While loop in C++*/
    Syntax:
    while(condition)
    {
        C++ statements;
    }

     Printing 1 to 40 using while loop
    int i=1;
    while(i<=40){
        cout<<i<<endl;
        i++;
    }

    Example of infinite while loop
    int i = 1;
    while (true)
    {
        cout << i << endl;
        i++;
    }

    /* do While loop in C++*/
        Syntax:
        do
        {
            C++ statements;
        }while(condition);

     Printing 1 to 40 using while loop
    int i=1;
    do{
        cout<<i<<endl;
        i++;
    }while(false);

    return 0;
}
