Write a program in C to calculate Factorial of a user given number. code example
Example 1: factorial c program using for loop
#include<stdio.h>
int main(){
int i,f=1,num;
printf("Enter a number: ");
scanf("%d",&num);
for(i=1;i<=num;i++)
f=f*i;
printf("Factorial of %d is: %d",num,f);
return 0;
}
Example 2: c code factorial function
#include <stdio.h>
int fact(int);
void main()
{
int no,factorial;
printf("Enter a number to calculate it's factorial\n");
scanf("%d",&no);
factorial=fact(no);
printf("Factorial of the num(%d) = %d\n",no,factorial);
}
int fact(int n)
{
int i,f=1;
for(i=1;i<=n;i++)
{
f=f*i;
}
return f;
}
