Question

error C2665: 'delete' : none of the 2 overloads can convert parameter 1 from type 'const unsigned

void AES::MixColumns()
{
byte matrix[4][4] = {
{0x02, 0x03, 0x01, 0x01},
{0x01, 0x02, 0x03, 0x01},
{0x01, 0x01, 0x02, 0x03},
{0x03, 0x01, 0x01, 0x02}};
const byte* temp = GFMultplyBytesMatrix((byte*)matrix, state);
for(int i = 0; i < 16; ++i)
{
state[i] = temp[i];
}
delete[] temp;
}
怎么解决这个错误啊？大神们

Answer 1

用const修饰*temp表示temp里面的值不能再进行改变了。。。。

Answer 2

delete[] temp;

temp不是new出来的，为什么要用delete呢
