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

Using boost::irange could be considered elegant (live example):

#include 
#include 

int main()
{
    for(auto i : boost::irange(0, 256) )
        std::cout << i << "\n";
    return 0;
}
