Question

If I have a string like:

const char* mystr = "Test Test Bla Bla \n Bla Bla Test \n Test Test \n";

How would I use the newline character ‘\n’, to split the string into an array of strings?

I’m trying to accomplish in C, the thing string.Split() does in C# or boost’s string algorithm split does in C++ .

Try to use the strtok function. Be aware that it modifies the source memory so you can’t use it with a string literal.

char *copy = strdup(mystr);
char *tok;

tok = strtok(copy, "\n");
/* Do something with tok. */
while (tok) {
    tok = strtok(NULL, "\n");
    /* ... */
}

free(copy);
