C program to display the factorial of a non-negative number.

Introduction:

In programming, a factorial is a mathematical function that is used to calculate the product of all positive integers less than or equal to a given number. It is often used in algorithms and mathematical calculations. In this article, we will explore a 'C' program that displays the factorial of a non-negative number.

The Program:

The first step in writing this program is to prompt the user to enter a non-negative integer. We will then use a for loop to calculate the factorial of the number entered by the user.

#include<stdio.h>
int main()
{
int n,fact=1,num;
printf("Enter any number\n");
scanf("%d",&num);
for(n=1;n<=num;n++)
{
fact=fact*n;
}
printf("The factorial of the given number is: %d",fact);
return 0;
}

Output:

Conclusion:

In conclusion, this 'C' program is a great example of how to calculate the factorial of a non-negative number using a for loop. The program prompts the user to enter a non-negative integer and then calculates its factorial using a for loop. It is a simple yet powerful example of how programming can be used to perform mathematical calculations efficiently. As a programmer, it is essential to have a good understanding of mathematical functions and algorithms, as they are a fundamental part of many programming applications.
