STRCPY implementation in C

I have mentioned two methods below.

Method 1:

// Program to implement strcpy 

#include <stdio.h>

char *my_strcpy(char *dest, const char *src){
    char *ptr;
    ptr = dest;
    while( *dest++ = *src++);
    return ptr;
}

int main(){
    char dest[6];
    char src[6] = "umesh"; // 5 characters + '\0'
    my_strcpy(dest, src);
    printf("dest = %s\n", dest);
    return 0;
}

* const char *src - const is used to restrict any change in the src

Method 2:

#include <stdio.h>

char *my_strcpy(char dest[], const char src[]){
    int i = 0; // loop variable
    while(src[i] != '\0'){
        dest[i] = src[i];
        i++;
    }
    dest[i]='\0';
    return dest;
}

int main(){
    char dest[6];
    char src[6] = "umesh"; // 5 characters + '\0'
    my_strcpy(dest, src);
    printf("dest = %s\n", dest);
    return 0; 
}
