CHARACTER FREQUENCY WITH ARRAYS [EOF not working]

[kdushyant297]

#include <stdio.h>
#include <ctype.h>
#include <assert.h>


//Frequency table of input
int main(int argc, char*argv[])
{
    int counts[26] = {0};
    int cypherChar = getchar();


    while(cypherChar != EOF)
    {
        if(isalpha(cypherChar))
        {
            counts[tolower(cypherChar) - 97]++;
        }
        cypherChar = getchar();
    }


    printf("Frequency Table\n");


    int i = 'a';
    while(i <= 'z')
    {
        printf("%c %d\n", i, counts[i - 'a']);
        i++;
    }
    return 0;
}

When I replace EOF with 10(ASCII value for Line Feed) it works fine but with EOF , NO OUTPUT!!

How do you send EOF?

At the start of a line, press ctrl-z (dos/wondows), or ctrl-d (unix/linux), then perhaps enter.
