Program to copy string without using strcpy()

/**
 * C program to copy one string to another string without using strcpy()
 */

#include <stdio.h>

int main()
{
    char text1[100], text2[100];
    int i;
    
    /* Reads the original string to be copied from user */
    printf("Enter any string: ");
    scanf("%s", &text1);
    
    /* Copies text1 to text2 character by character */
    i=0;
    while(text1[i]!='\0')
    {
        text2[i] = text1[i];
        i++;
    }

    //Makes sure that the string is NULL terminated
    text2[i] = '\0';

    printf("First string = %s\n", text1);
    printf("Second string = %s\n", text2);
    printf("Total characters copied = %d\n", i);

    return 0;
}

Program to copy string using strcpy()

/**
 * C program to copy one string to another string using strcpy()
 */

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

int main()
{
    char text1[100], text2[100];

    /* Reads the original string to be copied from user */
    printf("Enter any string: ");
    scanf("%s", &text1);


    /*
     * Copies text1 to text2 using strcpy()
     * Here first parameter of the function is destination string
     * And second is the source string
     */
    strcpy(text2, text1);

    printf("First string = %s\n", text1);
    printf("Second string = %s\n", text2);

    return 0;
} 

Happy coding ;)
