Question

Calculating the Factorial of a Number - PSEUDOCODE In mathematics, the notation n! represents the factorial of the nonnegative integer n. The factorial of n is the product of all the nonnegative integers from 1 up through n. For example: 7! = 1 × 2 × 3 × 4 × 5 × 6 × 7 = 5,040 and 4! = 1 × 2 × 3 × 4 = 24 Design a program that asks the user to enter a nonnegative integer and then dis-plays the factorial of that number.

Answer 1

#include <stdio.h>

int main() {
    int i = 1, num, f = 1;
    printf("Enter a positive integer: ");
    scanf("%d", &num);
    while (i <= num) {
        f *= i;
        i++;
    }
    printf("Factorial of %d is %d\n", num, f);
    return 0;
}
