I am confused with the output of below code when I execute it.

Code:

int add(int a, int b)
{
    cout<<\"inside int add function\"<

    the line cout< is expected to print your output:

    inside int add function
    inside float add function
    30
    70
    

    Thats because to print to cout firstly calls add(10.0f , 20.0f) and stores the output to a internal variable, then calls add(10, 20) and stores the output to another internal variable, and finally it prints the returned values. Something like this:

    float a = add(10.0f, 20.0f);
    int b = add(10, 20);
    cout << a << endl << b;
    

    In this case, if you want to print as you wish, try to print first one function, and then the other:

    cout << add(10.0f, 20.0f) << endl;
    cout << add(10, 20);
