Strtok Processing String Constants

The Strtok () function cannot handle the const char* directly, and a char array is obtained with strncpy, and the temp array is processed.

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
 
 
int main (void)
{
    Char *string = "t01:91+:123";
    Char tmp[16];
    char* s;
 
    /* Strtok can does with const char*, so I use the strncpy copy it to an char array *
    /strncpy (tmp, String, sizeof (string ));
 
    s = strtok (tmp, "T");
    printf ("String:%s\n", string); 01:91+:123
    s = strtok (S, ":");
 
    printf ("City ID:%s\n", s);
    return 0;
}

Update:

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

#include <string.h>
#include <stdio.h>
int main (void)
{
    char input[16]= "abc,d";
    char *p;
    P=strtok (Input, ",");
    if (p) printf ("%s\n", p);

    P=strtok (NULL, ","); Attention here.
    if (p) printf ("%s\n", p);
    return 0;
}

Output:

Abc
