Win Programming Practice (2) "C + +"

1, auto Let the compiler determine the type automatically, typeID return type, displacement operation

The source code is as follows:

//consoleapplication1.cpp: defines the entry point for the console application.

//

#include "StdAfx.h"

#include <iostream>

using std::cout;

using Std::endl;

using std::cin;

int Main ()

{

//auto automatic judgment type, typeid function return type

int x = 5000;

int y = 20;

Auto z1=x/y;

Auto z2=y/x;

Char temp;

cout << typeid(z1). Name ()<< Endl;

cout << typeid(Z2). Name ()<< Endl;

// bit arithmetic

int x1 = 0x0001;

int x2 = 0x0008;

int x3 = 0x0005;

int x4 = 0x000A;

int z3 = x1|x2; // or

int z4 = x1&x2; // with the

int z5 = x1|x3; // or

int Z6 = x1^x4; // XOR or

int Z7 = x2 >> 2; // Move right 2 bits, except 2^2

int Z8 = Z7 << 1; // Move left 1 bits, multiply by 2

cout << z3<<"<<Z4<<"<< Z5<<"<<z6<< " "<<Z7 << " " <<Z8<<Endl;

CIN >> temp;

return 0;
