Variable type and size

標題：變數型態與大小
VC++ (datatype.cpp)：

//Chapter 1 - datatype
#include <iostream>
using namespace std;

int main(void)
{
    cout << "type\tbyte" << endl;

    cout << "int\t"    << sizeof(int)    << endl; //4
    cout << "long\t"   << sizeof(long)   << endl; //4
    cout << "float\t"  << sizeof(float)  << endl; //4
    cout << "double\t" << sizeof(double) << endl; //8
    cout << "char\t"   << sizeof(char)   << endl; //1
    cout << "bool\t"   << sizeof(bool)   << endl; //1

    system("pause");
    return 0;
}
