Running through entire range of `unsigned char` in `for` loop

Question

I would like to run through the entire range of unsigned char in a for loop. Say I want to print all numbers from 0 to 255, how should I go about accom

Answer 1

You can break it up:

for (unsigned char i = 0; i < 16; ++i)
{
    unsigned char base=i*16;
    for (unsigned char j = 0; j < 16; ++j)
    {
        unsigned char val=base+j;
        std::cout << val << std::endl;
    }
}
