Answer 1

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

#define SIZE 64

int main()
{
   const char src[SIZE] = "https://www.collectivesolver.com/";
   char dest[SIZE] = "https://www.seek4info.com/";
   
   printf("Before memcpy: %s\n", dest);
   
   // void *memcpy(void *dest, const void * src, size_t n)
   // n − The number of bytes to be copied
   
   memcpy(dest, src, strlen(src) + 1);
   
   printf("After memcpy: %s\n", dest);
}
