Write a program that inputs a line of text, tokenizes the line with function str

Question

Write a program that inputs a line of text, tokenizes the line with function strtok and outputs the tokens in reverse order. (C Code)

Here is what I have so far.

#include <stdio.h>
#include <string.h>
#define SIZE 80

int main (void)
{
   // initialize array string
   char string[SIZE];
   char *reversestring[SIZE];
   char *tokenPtr; // create char pointer
   int count = 1;

   printf("Enter a line of text to be tokenized and reversed. ");
   fgets( string, SIZE, stdin );

   printf("%s %s %s ",
       "The string to be tokenized is:", string,
       "The tokens are:" );

   tokenPtr = strtok( string, " " ); // begin tokenizing sentence
   reversestring[0] = *tokenPtr;

   // continue tokenizing sentence until tokenPtr becomes NULL
   while ( tokenPtr != NULL ) {

       printf( "%s ", tokenPtr );
       tokenPtr = strtok( NULL, " " ); // get next token

       reversestring[count] = *tokenPtr;
       count++;
   } // end while

while(count!=0) {
   printf("%s ", reversestring[count]);
   count--;
}

} // end main

----------------------------

The OUTPUT looks like this.

Enter a line of text to be tokenized and reversed.

my name is

The string to be tokenized is:

my name is

The tokens are:

my

name

is

(null)

(null)

is

name

logout

Explanation / Answer

#include <stdio.h>
#include <string.h>
int main()
{
char line[30] = "i want to c this is revers";

char *tokens[30];

int max_tokens = sizeof(tokens)/sizeof(tokens[0]);
char *token_ptr;
int k;
printf("Original line of text: <%s> ", line);
token_ptr = strtok(line, " ");
for (k = 0; k < max_tokens && token_ptr != NULL; k++)
{
tokens[k] = token_ptr;
printf("tokens[%d]: <%s> ", k, tokens[k]);
token_ptr = strtok(NULL, " ");
}
printf("Number of tokens = %d ", k);


return 0;
}
