appending to an array

**mr_nice!** · 06-28-2004

I am going to sound really thick, so sorry!!

I have an array and I have filled it with elements (as in E in the example below) I would like then to add that array to another array and just add an element at the beginning or the end and would like to deal with the array as the whole instead of using a for loop to deal with each individual element in the array.

Is there a way I have tried F={23,E} but obviously this doesn't work. Any help would be great

nice

int i;
int E[9];
int Fup[10];
int Fdown[10];

for(i=0;i<9;i++)
E[i]=i;

Fup= {E,23};
Fdown={23,E};

C doesn't support such a thing. You'll need to use a function to do it for you. Conveniently enough, memcpy will do this for you:

Code:

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

int
main(void)
{
  int a[10] = {1,2,3,4,5};
  int b[] = {6,7,8,9,10};
  int i;

  memcpy(a + 5, b, 5 * sizeof(int));
  for (i = 0; i < 10; i++) {
    printf("%d\n", a[i]);
  }
}
