Thread: I need help counting letters., folk!

getchar() reads a character from the standard input, usually the
keyboard. getchar will also 'echo" the typed character to the standard output, usually the user screen.


I couldn't tell exactly how you wanted this program to work but here's an example.

Code:

#include <stdio.h>

int main(void)
{
  int char_count = 0;
  char next_char = '\0';

  printf(" Enter characters but not the # sign <>");
  for(;;)
  {
    next_char = getchar();
    switch(next_char)
   {
    case 'a': case 'b': case 'c':
    char_count++;
    printf(" a,b,c count = %d\n", char_count);
    break;

    default: break;
   } // end switch(next_char)

   if(next_char == '#')
   {
    puts(" I said not to enter the # sign!");
    break;
  } // end if(next_char == '#')
 } // end for(;;)
} // end int main(void)
