"WebAug 8, 2013 · Bit fields allow efficient packaging of data in the memory. Here is how bit fields are defined : struct info { int isMemoryFreed : 1; int isObjectAllocated : 1; } The above declaration tells the compiler that only 1 bit each from the two variables would be used. After seeing this, the compiler reduces the memory size of the structure. " - Bitfield array
