Hello Guys..
Welcome to lapmos.com
Today we will write a program which is how to calculate the factorial of a number given by user. First of all we should know what is factorial?
Factorial is a function that multiplies the number by every number below till 1. It's denoted by ( n! ).
For Example : 3! = 3 * 2 * 1 = 6
factorial of 0 (zero) is 1 = 0! = 1
Now Let's Start the Code.....
#include<stdio.h>
int main(){
int n;
printf("Enter the number : ");
scanf("%d", &n);
int fact = 1;
for(int i=1; i<=n; i++){
fact = fact * i;
}
printf("The factorial of %d! is %d", n, fact);
return 0;
}
Output :
Enter the number : 5
The factorial of 5! is 120
