    Yes, It will return the value 20*20 = 400 Example: #include <stdio.h> int f1(int, int); /* Function prototype */ int f2(int); /* Function prototype */ int main() { int a = 2, b = 3, c; c = f1(a, b); printf("c = %d\n", c); return 0; } int f1(int a, int b) { return ( f2(20) ); } int f2(int a) { return (a * a); } Output:
    c = 400
