Question

Is there any pre-defined function in C that can split a string given a delimeter? Say I have a string:

"Command:Context"

Now, I want to store “Command” and “Context” to a two dimensional array of characters

char ch[2][10]; 

or to two different variables

char ch1[10], ch2[10];

I tried using a loop and it works fine. I’m just curious if there is such function that already exists, I don’t want to reinvent the wheel. Please provide a clear example, thank you very much!

You can use strtok

Online Demo:

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

int main ()
{
    char str[] ="Command:Context";
    char * pch;
    printf ("Splitting string \"%s\" into tokens:\n",str);
    pch = strtok (str,":");
    while (pch != NULL)
    {
        printf ("%s\n",pch);
        pch = strtok (NULL, ":");
    }
    return 0;
}

Output:

Splitting string "Command:Context" into tokens:
Command
Context
