WebThere's 8 bits to the byte. The _t means it's a typedef. So a uint8_t is an unsigned 8 bit value, so it takes 1 byte. A uint16_t is an unsigned 16 bit value, so it takes 2 bytes (16/8 = 2) The only fuzzy one is int. That is "a signed integer value at the native size for the compiler". WebJan 5, 2024 · Similarly, for int it is 4 bytes, so ptr++ in case of int will be adding 0x04 to the address stored in the pointer. Pointer data type is a special kind of variable which are meant to store addresses only, instead of values (integer, float, double, char, etc). It knows how many bytes the data is stored in.

WebThe short answer is that it depends. When we say that a system is 32-bit, this could mean that the native integer is 32 bits wide, that the native address (i.e. pointer size) is 32 bits wide, or both. On top of that, not every architecture uses a flat memory model (for example, see x86 memory segmentation ). This further complicates matters.
