2. Write a C program to find factorial of given number.

#include<stdio.h>

#include<conio.h>

void main()

{

    int no,i,sum=1;

    clrscr();

    printf("enter number: ");

    scanf("%d",&no);

    for(i=0; no>0; i++)

    {

        sum = sum * no;

        no = no - 1;

    }

    printf("\nfactorials is: %d",sum);

    getch();

}

/*      output:

enter number: 5

factorials is: 120

*/
