初学C++ 之 输入输出（IDE：vs2013）

#include <iostream>　　//引用头文件（输入输出）

using namespace std;　　//引用命名空间，方便使用输入输出语句

class MathMethod
{
public:
    int a;
    int b;
    MathMethod(int aa, int bb);
    ~MathMethod();
    int AddInt();
};

MathMethod::MathMethod(int aa, int bb)
{
    a = aa;
    b = bb;
}
MathMethod::~MathMethod(){}

int MathMethod::AddInt()
{
    return a + b;
}

int AddInt(int a, int b)
{
    return a + b;
}

int main()
{
    int abc(11);
    int adc[]{ 22, 33 };
    for (int i = 0; i < 2; i++)
    {
        cout << adc[i] << endl;
    }

    char ch;
    cin >> ch;//输入
    cout << ch << endl;//输出
    wchar_t wch = 'a';
    cout << wch << endl;//输出ascll值

    int a, b;
    cin >> a;
    cin >> b;
    int c;
    c = AddInt(a, b);
    MathMethod mm(a, b);
    int d = mm.AddInt();
    cout << "a + b = " << c << endl;
    cout << "a + b = " << d << endl;
    system("pause");
    return 0;
