int fac (int n) { if (n < 0) return -1; //n must be positive if (n <= 1) return 1; return n * fac (n-1); } n <= 1 will be the condition to exit our recursion. Let's say n is 3. We get 3 * fac (2), but 2 is also bigger than one, so we get 3 * 2 ...
Factorial Calculator This is a simple C program that calculates the factorial of a given non-negative integer. Features Calculates the factorial of a number entered by the user. Handles input validation for non-negative integers. Allows the user to retry with a new input if desired. Requirements...
