If you take an integer and cast its address to a uint8_t* and manually step through the bytes you’re on your own. Reply RiverboatTurner ... WebIn code ported from other platforms, especially 8-bit or 16-bit platforms, the data types may have had different sizes. For example, int may have been represented as 16-bits. If this size has been relied on, some of the code may need updating to make it more portable.

WebA byte is a sequence of 8 bits The "leftmost" bit in a byte is the biggest. So, the binary sequence 00001001 is the decimal number 9. 00001001 = (2 3 + 2 0 = 8 + 1 = 9). Bits are numbered from right-to-left. Bit 0 is the rightmost and the …
