#include <stdio.h>#include <string.h>int main(){//char sentence[] = "This is a sentence with 7 tokens";char sentence[] = "first,second.three four,five.";printf("The string to be tokenized is:%s\n", sentence);printf("\nThe tokens are:\n");char *tokenPtr = strtok(sentence, " ,.");while(tokenPtr != NULL) {printf("%s\n", tokenPtr);tokenPtr = strtok(NULL," ,.");}printf("After strtok, sentence = %s\n", sentence);return 0;}

$ gcc -o str7 str7.c
$ ./str7
The string to be tokenized is:first,second.three four,five.
