Consider the following C program:
#include <stdio.h>
int g(int n) {
return (n + 10);
}
int f(int n) {
return g(n * 2);
}
int main() {
int sum, n;
sum = 0;
for (n = 1; n < 3; n++)
sum += g(f(n));
printf("%d", sum);
return 0;
}

Correct answer: 46
Short answer: 46
Explanation:
g(n) returns n + 10.
f(n) calls g with n * 2, so f(n) = g(n * 2) = (n * 2) + 10 = 2n + 10.
The expression g(f(n)) equals f(n) + 10 = (2n + 10) + 10 = 2n + 20.
The loop runs for n = 1 and n = 2 (since n < 3). For n = 1, g(f(1)) = 2*1 + 20 = 22. For n = 2, g(f(2)) = 2*2 + 20 = 24.
Sum = 22 + 24 = 46, which is printed by printf.
Output: 46
