==Add spaces to the end of a string==



   
<source lang="cpp">
#include <stdio.h>
#include <string.h>
void pad(char *s, int length);
int main(void)
{
  char str[80];
  strcpy(str, "this is a test");
  pad(str, 40);
  printf("%d", strlen(str));
  return 0;
} 
void pad(char *s, int length)
{
  int l;
  l = strlen(s); /* its length */
  while(l<length) {
    s[l] = " "; /* insert a space */
    l++;
  }
  s[l]= "\0"; /* strings need to be terminated in a null */
}

==Replace space with dash==


   
<source lang="cpp">
  
#include <stdio.h>
void sp_to_dash(const char *str);
int main(void)
{
  sp_to_dash("this is a test");
  return 0;
}
void sp_to_dash(const char *str)
{
  while(*str) {
    if(*str== " ") 
        printf("%c", "-");
    else 
        printf("%c", *str);
    str++;
  }
}

== Sequentially truncate string if delimiter is found==


   
<source lang="cpp">
#include <stdio.h>
#include <string.h>
int main(void)
{
  char *p;
  p = strtok("The summer soldier, the sunshine patriot", " ");
  printf(p);
  do {
    p = strtok("\0", ", ");
    if(p) printf("|%s", p);
  } while(p);
  return 0;
}

==Truncate string by delimiter: how to use strtok ==



   
<source lang="cpp">

#include <stdio.h>

int main ()
{
  char str[] ="This is a sample string, just testing.";
  char *p;
  
  printf ("Split \"%s\" in tokens:\n", str);
  
  p = strtok (str," ");
  
  while (p != NULL)
  {
