c++Learning

1.函数指针,类似于iOS的代码块block,将一段代码注入到方法中,在代码中执行

#include

using namespace std;

void testInt(int a){

cout<<"i am in the method";

}

void testTheMethod(void(*method)(int a)){

cout<<"i am in the right place";

method(4);

}

int main(){

void(*method)(int a)=NULL;

method=&testInt;

testTheMethod(method);

return0;

}

2.泛型定义

template
