How to use strlen with a pointer to an array of pointers to strings in C

Answer 1

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

int main() {
    // Array of pointers to strings // NULL == end
    const char *strings[] = {"C programming", "general-purpose", "programming", "language", NULL}; 
    const char **ptr = strings; // Pointer to the array of pointers

    // Iterate through the array of pointers
    while (*ptr != NULL) {
        printf("String: %s, Length: %zu\n", *ptr, strlen(*ptr));
        ptr++; // Move to the next pointer
    }

    return 0;
}
