所谓多重继承就是一个儿子有好几个爹，然后一个人继承了这几个爹的财产。只需注意构造顺序即可，反正析构的顺序也是一样的。

#include <iostream>
#include <string.h>
using namespace std;class base_a
{
public:base_a(const char *str){strcpy(this->str, str);}void show(){cout << "str=" << str << endl;}private:char str[1024];
};class base_b
{
public:base_b(float f){this->f = f;}void show(){cout << "f=" << f << endl;}private:float f;
};class base_c : public base_a, public base_b
{
public:base_c(const char *str, float f, const char *p, int size) : base_b(f), base_a(str), size(size){this->p = new char[size];memset(this->p, 0, size);strcpy(this->p, p);}void show(){base_a::show();base_b::show();cout << "p=" << p << endl;cout << "size=" << size << endl;}~base_c(){delete []p;}private:char *p; // 指向大小为size的堆空间int size;
};int main(int argc, char const *argv[])
{base_c c("hello", 1.1, "world", 10);c.show();return 0;
}
