unused memory using 32 bit integer in C
- by endmade
I have the folowing struct of integers (32 bit environment):
struct rgb {
int r;
int g;
int b;
};
Am I correct in saying that, since rgb component values (0-255) only require 8-bits(1 byte) to be represented, I am only using 1 byte of memory and leaving 3 bytes unused for each component?
Also, if I instead did the following:
struct rgb{
unsigned int r:8;
unsigned int g:8;
unsigned int b:8;
};
Assuming that what I said above is correct, would using this new struct reduce the number of unused bytes to 1?
