C Program Find the Length of the Linked List using Recursion

This C Program uses recursive function & calculates the length of a string. The user enters a string to find it's length.

    #include <stdio.h>

    int length(char [], int);

    int main()

    {

        char word[20];

        int count;

        printf("Enter a word to count it's length: ");

        scanf("%s", word);

        count = length(word, 0);

        printf("The number of characters in %s are %d.\n", word, count);

        return 0;

    }

    int length(char word[], int index)

    {

        if (word[index] == '\0')

        {

            return 0;

        }

        return (1 + length(word, index + 1));

    }
