Question
Consider the following C program:The output of the given C program is ________. (Answer in integer)
#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 to 46
Solution
Let's analyze the functions:
The program prints the value of
1.
g(n) returns .2.
Now analyze the f(n) calls g(n*2), so it returns .main function:sumis initialized to 0.- The loop runs for
n = 1andn = 2(sincen < 3). - Inside the loop,
sum += g(f(n))is executed.
g(f(n)):f(n)returns .g(x)returns .- Therefore,
g(f(n))returns .
- Value added = .
sum= .
- Value added = .
sum= .
n becomes 3.The program prints the value of
sum, which is 46.Continue learning with Success Tracker
