Hi, I am relatively new to programming and reading through Kernigan and ritchies book. Everything was going fine untill i encountered this question that has struck me for a while. The question is :
" write a program that copy it's input to it's output replacing each string of one or more blanks by a single blank "
The output presented below prints -1 and as in the exercise i would like that more than one blank is produced as a blank. What am i doing wrong? (probably a lot)
Code:
#include <stdio.h>
#include <stdlib.h>
int main(VOID)
{
int c;
int blanks = 0;
while((c = getchar()) != EOF){
if(c == ' ')
putchar(c);
if(c != ' ')
putchar(blanks);
}
blanks = c;
printf("%d,%d", c, blanks);
