自己运行看看。。。include<iostream>using namespace std;class A{private :int val;public :A(int i=0):val(i) {}A& operator =(const A& B){return *this;}int& gt_val(){ return val;}}a,b(1);int main(){a=b;cout<...
在前面的makefile例中有许多重复内容,例如,生成hello和hello1的命令类似,生成hello.o和hello1.o的命令也类似,除了编译或链接的文件不一样外,其它均相同,这时,我们就可以使用后缀规则。首先看一个双后缀的例子: 图4 使用双后缀规则的makefile例 后缀规则使用特殊的目标名“.SUFFIXES”。 第一行中.SUFFIXES的依赖...

所以我将这一句改为class derived :public base 然后下边的调用改成了obj.base::show();附代码 include<iostream>using namespace std;class base{private:int m;public:base(int a) :m(a) {}void show() const{cout << "m:" << m << endl;}};class derived :public base{int n;...
