Question

Consider the C function given below.
int f(int j) {
static int i = 50;
int k ;
if (i ==j) {
printf("something");
k = f(i);
return 0;
}
else return 0;
}
Which one of the following is TRUE?

• A. The function will exhaust the runtime stack or run into an infinite loop when j = 50.
• B. The function prints the string something for all values of j
• C. The function returns 0 for all values of j.
• D. The function returns 0 when j = 50.

Answer 1

The correct option is A The function will exhaust the runtime stack or run into an infinite loop when j = 50.

$f\left(50\right)\text{goes into infinite loop by calling}$
f(i) recursively for i = j = 50
