reiinitialsing a variable

hi can anyone help me here;

i have a while loop that carries out some operations on an array ive named arrayQ - at the end of the loop i want to reinitialise arrayQ back to its original value which i have stored in an array called array_Qcopy.

for some reason the code below doesnt work, on the first loop through the while statement - the original value changes to the modified one - instead of the modified one changing back to the original.

Code:

for( k = 0; k < size; k++)		
{array_Q[k] = array_Qcopy[k]; }

please help !!!

Without seeing how you declared (and used) these arrays prior to this, it's hard to say whether you're doing the right thing or not.

You should also probably perform your operations on the copy, rather than the original. std::vector might be a better choice though.
