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

Answer 1

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

int main() {
    // Array of pointers to strings
    const char *strings[] = {"C programming", "general-purpose", "programming", "language"};
    int numStrings = sizeof(strings) / sizeof(strings[0]); // Calculate number of strings

    // Iterate through the array and print the length of each string
    for (int i = 0; i < numStrings; i++) {
        printf("Length of string \"%s\" is: %zu\n", strings[i], strlen(strings[i]));
    }

    return 0;
}


/*
run:

Length of string "C programming" is: 13
Length of string "general-purpose" is: 15
Length of string "programming" is: 11
Length of string "language" is: 8
