计算 long long, long double 字节大小

include

int main()
{
int a;
long b;
long long c;

double e;
long double f;


printf("Size of int = %ld bytes \n", sizeof(a));
printf("Size of long = %ld bytes\n", sizeof(b));
printf("Size of long long = %ld bytes\n", sizeof(c));

printf("Size of double = %ld bytes\n", sizeof(e));
printf("Size of long double = %ld bytes\n", sizeof(f));

return 0;

}
运行结果：

Size of int = 4 bytes
Size of long = 8 bytes
Size of long long = 8 bytes
Size of double = 8 bytes
Size of long double = 16 bytes
