    I think you have got :
    char buff[256]
    which declares an array of 256 chars (and is used as a buffer maybe)

    char buffer[256] is just an array in which input is stored.
    Try :

    #include <stdio.h>
    #include <string.h>

    int main(void)
    {
    char buffer[256];
    printf(" enter name and press enter ");
    fgets(buffer,256,stdin);
    printf(" \nyour name has %d chars and spaces\n",strlen(buffer));
    return 0;
    }

    >stdin( buffer )-1);

    That was what went wrong, stdin is not a function.

    It's not for anything in this case, because it was used wrong.
    What it was probably supposed to be for, was use with fgets, which was actually using it incorrectly anyway.
    The '-1' is not needed at all for correct usage here.

    Hope is the first step on the road to disappointment.
