Question

c program

my c program for factorial is not giving any value in the output box though it shows no errors

 #include<stdio.h>
    main()
    {
        int a,n,t=1;
        printf("enter the number\n");
        scanf("%d",a);
        for(n=1;n<=a;n++)
        {
            t*=n;
        }
        printf("the factorial is %d",t);
    }

the image

`scanf("%d",&a);` Also get an up-to-date C book. Looks like you are using K&R or some other *old* book. — Eugene Sh., Jul 31 '19 at 14:14
wow, that was quick, thanks. that was a stupid error. I was not referring to any book, just freewheeling. — Kushal, Jul 31 '19 at 14:20
A free-wheeler should know that the correct definition is `int main(void)` — Weather Vane, Jul 31 '19 at 14:25

You'll have to pass address of variable a like this.. scanf("%d", &a);
