Thread: Reqd clarification

Can someone tell me what is difference between using

Code:

#pragma pack(push,aaa, 1)

struct check 
{
	int a;
	char b;
};

#pragma pack(pop,aaa)

&

Code:

#pragma pack(1)

struct check 
{
	int a;
	char b;
};

in both case size is 5. what exactly is the difference?

In one case you can pop the pragma (go back to default packing). In the other case you can't.
