In this tutorial, we are going to write a C Program to find the factorial of a number using a function in C Programming with practical program code and step-by-step full complete explanation.
C Program to find the factorial of a number using a function
#include<stdio.h>
#include<conio.h>
void main()
{
int a,f;
int fact(int);
clrscr();
printf("Enter a number: ");
scanf("%d",&a);
f=fact(a);
printf("factorial = %d",f);
getch();
}
int fact(int x)
{
int fact=1, i;
for(i=x;i>=1;i--)
fact=fact*i;
return(fact);
}
Output
Enter a number: 5 Factorial = 120
