1 Iterate over Words in String using strtok function

In this example,

We include the string.h header file.

We then iterate over the resulting tokens using a while loop.
Finally, we print each word to the console.

C Program

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

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