Factorial Calculator in C

//this is a small program that will get you how to calculate factorial in C

//------------------------------------------------------------------------------

#include<stdio.h>

#include <conio.h>

int main()

{

int w=1, x ,  y , z=1;

printf("factorial theorem\n");

scanf("%d",  &y );

for (x=1;x<y ; x++){

    z=x*z;

    printf("%d!=%d\n",w, z);

    w++;

    

}

getch();

}

/*

x=loop variable.......

y=limit of table

w=value--jis ka factorial at the moment liya jaa rha hai i.e. 0! ,1!,2!....

z= answer of factorial
