C Program to Copy One String to Another using Recursion

C Program to Copy One String to Another using Recursion

This C Program uses recursive function & copies a string entered by user from one character array to another character array.

    #include <stdio.h>

    void copy(char [], char [], int);

    int main()

    {

        char string1[20], string2[20];

        printf("Enter string to copy: ");

        scanf("%s", string1);

        copy(string1, string2, 0);

        printf("Copying success.\n");

        printf("The first string is: %s\n", string1);

        printf("The second string is: %s\n", string2);

        return 0;

    }

    void copy(char string1[], char string2[], int index)

    {

        string2[index] = string1[index];

        if (string1[index] == '\0')

            return;

        copy(string1, string2, index + 1);

    }
