# Program to Print Factorial of a Number in C

There are lots of ways to print factorial of a number in C programming languages. I have listed down some common methods to print factorial of a number in C.

### Ways to Print factorial of a Number

1. Factorial of Number using for Loop.
2. Factorial of a Number using While loop.
3. Factorial of a Number using do While loop.
4. Factorial of a Number using Recursion.
5. Factorial of a Number using Function call.

### What is the Factorial of a Number in C?

Factorial of a number (N) is defined as the product of all numbers from 1 to N.Logic used in all the methods to print factorial of a number is that we will input a number from the user and then multiplying all numbers by decreasing/increasing it until the loop reaches 1 or N. Above code is for only Positive numbers You can add an If else statement to check whether a number is positive or negative. If the number is negative then Output should be " Negative number's Factorial doesn't exist.

## Find Factorial of a number using For loop in C

//@Courpedia
#include<stdio.h>
void main()
{
int i,factorial=1,n;
printf("enter the number\n");
scanf("%d",&n);
for(int i=1;i<=n;i++)
{
factorial=factorial*i;
}
printf("%d"factorial);
}

Another way to find the factorial of a number using c

//@Courpedia
#include<stdio.h>
void main()
{
int i,n,fact=1;
printf("enter the number\n");
scanf("%d",&n);
for(i=n;i>=1;i--)
{
fact=fact*i;
}
printf("%d"fact);
}

### Find Factorial of a number using While loop in C

//@Courpedia
#include<stdio.h>
void main()
{
int i,n,fact=1;
printf("enter the number\n");
scanf("%d",&n);
int temp=1;
while(temp<=n)
{
fact=temp*fact;
temp++;
}
printf("%d"fact);
}

### Find Factorial of a number using Do While loop in C

//@Courpedia
#include<stdio.h>
void main()
{
int i,n,fact=1;
printf("enter the number\n");
scanf("%d",&n);
int temp=1;
do{
fact=fact*temp;
temp++;

}while(temp<=n);
printf("%d"fact);
}

### Find Factorial of a Number using Recursion in C

Recursion means accessing the function itself in the same function.

//@courpedia
#include <stdio.h>
unsigned long fact(unsigned long int n)
{
if (n == 0)
{
return 1;
}
else
{
return(n * fact(n - 1));
}
}
int main(int argc, char *argv[])
{
unsigned long  n = 0;
unsigned temp = 0;
printf("Enter the number ");
scanf("%lu"&n);
temp = fact(n);
printf("  %d \n"temp);

return 0;
}

### Find Factorial of a number using Function in C

//courpedia
#include<stdio.h>
int fact(int);
void main()
{
int n;
printf("enter the number\n");
scanf("%d",&n);
int b=  fact(n);
printf("%d"b);

}
int fact(int n)
{
int result=1;
for(int i=1;i<=n;i++)
{
result=result*i;
}
return result;

}
