Introduction

The following program adds a dash for each space in its string argument.

The const in the parameter declaration ensures that the code inside the function cannot modify the parameter.

Demo Code

#include <stdio.h>

void sp_to_dash(const char *str);

int main(void)
{
   sp_to_dash("this is a test");

   return 0;/*from w w  w  .  j av a2  s  .c o  m*/
}

void sp_to_dash(const char *str)
{
   while (*str) {
      if (*str == ' ') printf("%c", '-');
      else printf("%c", *str);
      str++;
   }
}
