How do I quickly erase an array?

[BeyondtheTech]

This might be simple C++ command or procedure, but how does one erase an array quicker than this?

Code: Select all

for (i1=0; i1<10; i1++)
   for (i2=0; i2<10; i2++)   
      for (i3=0; i3<10; i3++)
         array[i1][i2][i3]=0;

The fastest way to erase is use the memset function.

If your array is this:
int array[5][3][7];

Erase with:
memset(array, 0, 5*3*7*sizeof(int));
