Problem with STREAM INPUT for C Program

I'm having a problem with a program I wrote that should show the average number of letters per word after EOF (Ctrl 'Z') is entered. I think the program is reading the input as a stream of characters OK. My average is not working. I'd appreciate if someone could identify where I'm going wrong.

----------------------------------------HERE IS MY CODE-----------------------------------------------

#include <stdio.h>

int main()
{

    int ch; /* some character */
    int count=0; /* count letters */

    printf("Enter input ending with ctrl 'Z' or ctrl 'D':\n");

    ch = getchar(); /* get first input */

    /* loop till eof entered */
    while(ch != -1)
    {

       // check for now space
       if(ch > ' ')
         count++; /* increment count */

       ch = getchar(); /* get next input */
    }

    /* report number of letters */
    printf("Number of letters %d\n",count);


    printf("\n");
    getchar(); /* pause */

    return 0;
}

Hi computerese,

There's no code for averaging here. To find the average letters per word you need to count the number of words AND count the letters in all the words. Divide one by the other to get the average.

You could do it like this:

       if(ch == ' ')
         spaceCount++; /* increment space count */
       else
         letterCount++;
