We iterate over the substrings and print them.

C Program

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

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

Output

Hello
World
