Is there some c++ proposal for Integer literal for fixed width integer types like this? // i's type is unsigned int auto i = 10u; // j's type is uint32_t auto j
The below code is trying to extract the red, green and blue channel of a pixel value and performing an arithmetic with another set of RGB values. It seems that
