C program to find factorial of user given number

C program to find factorial of user given number – for beginner

C program to find factorial | Let’s assume, Factorial of a positive number ‘n’ given by user

factorial of n(n!) = 1 *  2 * 3 * ……. upto Nth number.

Factorial of negative number is not possible. In simple word it doesn’t exists. ok lets start our program:

Find factorial of a user given number using C language.

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

Ascending and Descending order using C programming language

C program to find factorial of given number

#include<stdio.h>
#include<conio.h> 
void getFactorial(int,int *); //function
int main(){
 int i,factorial,n;
 
 printf("Enter a number: ");
 scanf("%d",&n);
 
 getFactorial(n,&factorial);
 printf("Factorial of %d is: %d",n,*factorial);
 
 return 0;
}
 
void getFactorial(int n,int *factorial){
 int i;
 
 *factorial =1;
 
 for(i=1;i<=n;i++)
 *factorial=*factorial*i;
}
