1. Here is a recursive function that is supposed to return the factorial. Identify the line(s) with the
logical error(s). Hint: This compiles and runs, and it computes something. What is it?
int fact( int n ) //a
{
int f = 1; //b
if ( 0 == n || 1 == n ) //c
return f; //d
else
{
f = fact(n - 1); //f
f = (n-1) * f; //g
return f; //h
}
}
Solution
#include long int multiplyNumbers(int n); int main() { int n; printf("Enter a positive integer: ");
scanf("%d", &n); printf("Factorial of %d = %ld", n, multiplyNumbers(n)); return 0; } long int
multiplyNumbers(int n) { if (n >= 1) return n*multiplyNumbers(n-1); else return 1; }
