C++知识点案例 笔记-1

1.重载函数
2.内联函数
3.New、Delete
4.重载与、const形参
5.常数据成员
6.静态成员函数

==重载函数==
#include 
using namespace std;
void add(int x,int y)
{
    cout< 
 
==内联函数==
#include 
//#include 
using namespace std;
inline void love(int i)
{
    cout<<"我喜欢你"< 
 
==New、Delete==
#include 
#include 
using namespace std;
int main()
{
    int *pi= new int(10);
    cout<<"*pi:"<<*pi< 
 
==重载与、const形参==
#include 
using namespace std;
void func1(const int *x)
{
    cout<<"常量指针:"<<*x< 
 
==常数据成员==
#include 
using namespace std;
class circle
{
public:
    circle(double r);
    double c_c();
private:
    double R;
    const double pai;
};
circle::circle(double r):pai(3.1415926)
{
    R = r;
}
double circle::c_c()
{
    return 2*pai*R ;
}
int main()
{
    cout<<"请输入半径："<>pk;
    circle q_c(pk);
    cout<<"计算得周长为："< 
 
==静态成员函数==

#include 
#include 
using namespace std;
