#include <stdio.h>

int main()
{
FILE *file;
int alpha[26]={0};
const char fileName[]="abc.txt";
char ch;
file= fopen(fileName,"r");
if(file == NULL)

printf("cannot open the %s",fileName);
exit(8);
}
do
{
ch=fgetc(file);
char c = tolower(ch);
switch(c)
{
case'a': alpha[0]++;
break;
case'b': alpha[1]++;
break;
case'c': alpha[2]++;
break;
case'd': alpha[3]++;
break;
case'e': alpha[4]++;
