Solve this

Question

What is answer and why?

int a=2;
int b=3;
while(--b)
{ ++a
cout<<a ;
}

Answer 1

Again, 34!
I suggest you use a pen and paper and write down this program on it. Then trace the code flow and count how many times variable a is incremented.

Answer 2

Trace it my friend. BTW, your code have some syntax error.

Answer 3

int a=2;
int b=3;

while(--b) // first loop: b=2, a=3
// second loop: b=1, a=4
// third loop: b=0 and exit
{ ++a
cout<<a ;
}

Answer 4
