Hi..all c Expert please help me with token...

Code:

---


char *reverseWord(char* text){
  int i, j, c;
  char *ptr;
  char temp[STRING];
  int stringLength;

  stringLength = strlen(text);
  ptr = text;
  strcpy(temp, text);

  for (i=0, j=stringLength-1; j > i; i++, j--)
  {
    c = text[i];
    text[i] = text[j];
    text[j] = c;
 }
  return ptr;
  }

  void reverse() {
  int i, j;
  int c;
  char text[STRING + 1];
  char outputString[STRING + 1];
  char *tokenPtr;
  char temp[STRING + 1];
  int stringLength;
  int *counter;

  countOption(2, counter);

  stringLength = strlen(text);
  get_input(text);
 
  strcpy(outputString, text);

  tokenPtr = strtok(text, " ");
  tokenPtr = reverseWord(tokenPtr);
  strcpy(temp, tokenPtr);

  while ((tokenPtr = strtok(NULL, " ")) != NULL) {
  tokenPtr = reverseWord(tokenPtr);
  strcat(temp, tokenPtr);
  }
  j = 0;
  for (i = 0; i < stringLength; i++) {
    outputString[i] = temp[j];
    j++;
 }
  printf("Reverse String %s\n", outputString);
  }

Hi...this code dun have compilation error but got some runtime error..when i try to reverse by word..it can't read to next word for example [ This is reverse] Output : [siht is reverse]
What is my problem??Can anyone help me..Please i will appreciate everythings if you help me..Thanks..

I just tried your code and got Output : [sihTsiesrever]

hi..thanks for replying me..but i solved the problem oredy..but can i know what compiler u r using??Because i am using borland. I really tested the code and get the wrong answer.But anyway thanks...

Hi, I compiled with Micrsoft Visual C++ 6..

> but got some runtime error
Here's a tip - saying what the error was helps.
We know you have a problem, we can tell that much simply from the existence of your post.

My guess is you did this

Code:

---

char *s = "This is reverse";
reverse( s );
// or
reverse( "This is reverse" );

---

Whereas you should have tried

Code:

---

char s[] = "This is reverse";
reverse( s );

---

The reason being that it is implementation specific as to whether you can write to string constants (and you do write to them with your strtok call). For some it works, and for others (like you), you get a memory fault of some description.

Ok...i had try it..and it works..thanks anyway..Cheers :)
