Question
The value printed by the following program is ______.
void f(int* p, int m){
m = m + 5;
*p = *p + m;
return;
}
void main(){
int i=5, j=10;
f(&i, j);
printf("%d", i+j);
}
Correct answer
30 to 30
Solution
Execution trace:
1.
main starts. i = 5, j = 10.2.
f(&i, j) is called. p points to i, m is a copy of j (10).3.Inside
f: m = m + 5 .4.
*p = *p + m . (Since p points to i, i is modified).5.
f returns.6.Back in
main: printf("%d", i+j) prints .Continue learning with Success Tracker
