**C Program**to

**print a Factorial of any given number**entered by the user.

## What is a Factorial of a Number?

The factorial of a number is equal to the multiplication of the number's factors. let's say we want to get the factorial of number 4. so the

**factorial**of number**5**is**1*2*3*4*5 = 120.**now let's make a**c program**to**print the factorial of a given number.**```
#include<stdio.h>
#include<conio.h>
void main()
{
int input, i, fact=1;
printf("Enter any number: ");
scanf("%d", &input);
for( i=1; i<=input; i++)
fact= fact*i;
printf("Factorial of %d is %d", input, fact);
getch();
}
```

### Output

### Explanation

Here first we include the two header files

**stdio.h**and**conio.h**. after that we declare the main function. and inside that, we declare the three variables**input**,**i**, and**fact**, and set the value of fact variable to 1. after that we print the message on the screen "**Enter any number:**" using**printf()**function. and then we scan the value that given or enter by the user in the input variable using the**scanf()**function.after that, we use the for loop to find the factorial of the given number. remember the for loop will increase the value of i and multiply with the fact variable. and the loop will run till the value of i will not equal the input variable.

now using the printf() function we print the factorial and the message on the output screen.
