Hello, what is the fastest way to add an array of integers, to a current array of integers? (in C++) just for clarity... int arr1[500]; // temp array int arr2[1000]; // array i want to append values to // fill arr1 with values // fill arr2 with 500 values so // one way is to append arr2 with arr1 is...... for (int i = 0; i < 500; i++) arr2[500+i] = arr; But is there a faster way???? Cheers Paul

I think you're looking for memcpy:


int arr1[500]; // temp array
int arr2[1000]; // array i want to append values to

for(int count=0; count<500; ++count) { // Fill arrays with values
arr2[count] = count;
arr1[count] = count+500;
}

memcpy(&arr2[500], arr1, 500*sizeof(int));


You might want to test that though [grin]

Eh yeah, that's what I meant too ;)
You could use CopyMemory, but is Windows specific, I believe.
