基本数据类型验证

#include <stdio.h>

typedef int INT;
typedef unsigned char BYTE;
typedef struct Q
{
    INT i;
    BYTE TEMP1;
    BYTE TEMP2;
    short s;
}DEMO; //4+1+1+2

int main()
{
    INT a;
    BYTE b;
    DEMO c;

    printf("%d,%d\n", sizeof(INT), sizeof(a));
    printf("%d,%d\n", sizeof(BYTE), sizeof(b));
    printf("%d,%d\n", sizeof(DEMO), sizeof(c));
    return 0;
}
