If you don't require soemthing reentrant, strtok is a standard function:

Code:

---

#include <stdio.h>
#include <string.h>

#define DELIM " "

int main(void)
{
    char buff[BUFSIZ];

    printf("Enter a string: ");
    fflush(stdout);

    if (fgets(buff, sizeof buff, stdin) != NULL) {
        char *sep = strtok(buff, DELIM);

        while (sep != NULL) {
            puts(sep);
            sep = strtok(NULL, DELIM);
        }
    }

    return 0;
}

If you do need a reentrant function, you'll have to write it yourself or use a nonstandard extension if your compiler supports one.

sorry, i havent typed it down that the string is stored in the 2D array having a maximum 80 words....

So copy each token into the array. Something like this:

Code:

---

#include <stdio.h>
#include <string.h>

#define DELIM  " "
#define MAXWORD 80
#define MAXLEN  20

int main(void)
{
    char words[MAXWORD][MAXLEN];
    char buff[BUFSIZ];
    int  ntokens = 0;
    int  i;

    printf("Enter a string: ");
    fflush(stdout);

    if (fgets(buff, sizeof buff, stdin) != NULL) {
        char *sep = strtok(buff, DELIM);

        while (sep != NULL) {
            strcpy(words[ntokens++], sep);
            sep = strtok(NULL, DELIM);
        }
    }

    for (i = 0; i < ntokens; i++)
        puts(words[i]);

    return 0;
}

THx u very much
by the way
i am a beginner of c, many times find many difficulty in writing programs, how can i improve my programming skills?

>how can i improve my programming skills?
Read lots of good code and try to imitate what you read. Eventually you'll find yourself writing good code with ease.

>how can i improve my programming skills?
Taking an English course would also help.
