C Program To Find Factorial | Learnt Hub

Hello friends, in this example, you will learn how to find factorials of the given number entered by the user in C programming language.

Before starting the program, we need to know about factorials of a number.

Factorials:-

The factorial of an integer is a number that is equal to the product of that number and all numbers smaller than that.

For Example:

Factorials of 5 is:

5!=5*4*3*2*1
To understand this program, you should have to study the following topics.

1. Operators
2. Conditions Statements
3. Loops

Code:

#include<stdio.h> int main() { int n,i,fact=1; printf("Enter a number to Factorial:\n "); scanf("%d",&n); for(i=n;i>=1;i--) { fact=fact*i; } printf("Factorial of number is=%d",fact); return 0; }

Output:

Enter a number to Factorial: 7

Factorial of number is= (7*6*5*4*3*2*1) 5040
