c++ delete a newed array by using delete[]

Question

I know in c++ delete a newed array by using delete[]. What I am wondering is, what if I just do delete without []. I saw something like this in our company code. And it does no crash the system. Is this also right?

u_char* binBuf2 = new u_char[bitCount + 1];
delete binBuf2;

thanks

it is not correct, but it will work anyways, on *some* platforms. Dont use — sp2danny, Feb 04 '15 at 21:10
_" I saw something like this in our company code."_ That sounds highly questionable, and should be fixed. — πάντα ῥεῖ, Feb 04 '15 at 21:16

No that is not the correct method of freeing up the memory.

Keep in mind that because something doesn't crash the system doesn't mean it's good practice
