strtok(): parse string into tokens

#include <stdio.h>
#include <string.h>
int main ()
{
  char str[50] ="Welcome-to-plus2net";
  char *p;
  p = strtok (str,"-");
  printf ("%s\n",p);
}

Welcome

strtok(main_string, delimiter_string);

#include <stdio.h>
#include <string.h>
int main ()
{
  char str[50] ="Welcome-to-plus2net";
  char *p;
  p = strtok (str,"-");
  printf ("%s\n",p); // Welcome
  p = strtok(NULL,"-");
  printf ("%s\n",p); // to
}

Example 1: Splitting a String Using Space as a Delimiter

This example demonstrates how to split a string into individual words using spaces as delimiters.

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

int main() {
    char str[] = "plus2net provides great tutorials";
    char *token = strtok(str, " ");
    
    while (token != NULL) {
        printf("%s\n", token);
        token = strtok(NULL, " ");
    }
    
    return 0;
}

Example 2: Splitting a String with Multiple Delimiters

Use multiple delimiters such as commas, spaces, and periods to split a string.

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

int main() {
    char str[] = "apple, banana, orange. grape";
    char *token = strtok(str, ",. ");
    
    while (token != NULL) {
        printf("%s\n", token);
        token = strtok(NULL, ",. ");
    }
    
    return 0;
}

apple
banana
orange
grape

Example 3: Tokenizing with User Input

This example allows the user to enter a string and choose a delimiter to split it.

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

int main() {
    char str[100], delim[10];
    
    printf("Enter a string: ");
    fgets(str, sizeof(str), stdin);
    
    printf("Enter a delimiter: ");
    scanf("%s", delim);
    
    char *token = strtok(str, delim);
    
    while (token != NULL) {
        printf("%s\n", token);
        token = strtok(NULL, delim);
    }
    
    return 0;
}

Enter a string: Hello, World!
Enter a delimiter: ,
Hello
 World!
