18 - WAP to Implement own strcpy() function without using strcpy() in C

This program prints the Length of String by function without using strcpy().

• This code implements a own strcpy() function to calculate the length of a given string without using strcpy()

/* Program to implement own strcpy function */
#include 
/* strcpy function */
char* own_strcpy(char *dest, const char *src)
{
    /* Storing initial address of dest pointer */
    char *temp = dest;
    /* copy of string from source to destination up to null terminated character */
    while (*dest++ = *src++);
    return temp;
}
/* Main program function */
int main()
{
    /* Declaring source & destination strings */
    char src_str[50];
    char dest_str[50];
    char *dest = NULL;
    printf("Enter any String = ");
    gets(src_str);
    /* Own string copy function call */
    dest = own_strcpy(dest_str, src_str);
    printf("Destination String is : %s \n",dest);
    return 0;
}
