Thread: program to calculate number blanks, tabs and new lines in the input at command prompt

I am novice in c programming and have written the following program to calculate the number of blanks, tabs and new line characters in the input at the command prompt. I am using turbo c compiler and when i run this program i am getting correct output for number of tabs but for the other two the result is something which is very high and i can't understand. Please help.

Code:

#include<stdio.h>
main()
{
  int nb,nt,nl;
  int c;
  while((c=getchar())!=EOF)
  {
    if(c == ' ')
      nb++;
    if(c == '\t')
      nt++;
    if(c == '\n')
      nl++;
  }
  printf("blanks: %d\ntabs: %d\nnewlines: %d\n");
}

example run:
input:
this is the last
time i am attempting to run
this program before posting

output:
blanks:861
tabs: 4
newlines:230

The output for tabs is as expected since i have given 4 tab characters but the remaining two values is a bit confusing.
i have used ctrl+z to terminate the program if that makes any difference.

thanks a lot, i have been trying to figure it out since this morning. this worked.
