2) Write a C program finds factorial value of given number using for loop

source file name: factval.C

#include<stdio.h> 

int  main()

{

int n,f=1;

//clrscr();

printf("enter any number ");

scanf("%d",&n);

for (;n>0;n--)

{

f=f*n;

}

printf("factorial value =%d ",f);

//getch();

return 0;

}

 

Output:

enter any number 4

factorial value = 24

enter any number 6

factorial value = 720
