copy array in c code example

Example 1: copy array of integers in c

int * intdup(int const * src, size_t len)
{
   int * p = malloc(len * sizeof(int));
   memcpy(p, src, len * sizeof(int));
   return p;
}

Example 2: c copy array

#include <stdio.h>

int main() {
   int original[10] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 0};
   int copied[10];
   int loop;
   
   for(loop = 0; loop < 10; loop++) {
      copied[loop] = original[loop];
   }
   printf("original -> copied \n");
   
   for(loop = 0; loop < 10; loop++) {
      printf("   %2d        %2d\n", original[loop], copied[loop]);
   }

   return 0;
}
