Question

Consider the following C++ program:

#include <iostream>
using namespace std;

void f1(int);
void f2(int);
void f3(int);

int main()
{    
    f1(10);
    return 0;
}

void f1(int n)
{    
    f2(n + 5);
}

void f2(int n)
{    
    f3(n - 2);
}

void f3(int n)
{    
    cout << n << endl;    // LINE 1
}

Just before the program statement marked with the comment "LINE 1" is executed, how many stack frames will be on the program call stack?

Answer 1

SOL:

Soi: from The program execution will starts Main. First the main () is called and main() is pushed to stack e Next FIC) is called from mainc so FIC) is pushed to stack Neuct Fac) is called foom fic) so pushed E2C) is to stack from fa() So &3() is called to stack is Pushed on follows So The Stack looks like as 143(13) f2 (15) Telco) maincal - stack in Stack 4 of frames So The nomber
