Answer 1

#include <iostream>

using std::cout;
using std::endl;

struct String {
	String(char *_p);
	~String();
	void print();
private:
	char *p;
};

String::String(char *_p) {
	p = new char[strlen(_p) + 1];
	if (!p) {
		cout << "new error" << endl;
		exit(1);
	}
	strcpy(p, _p);
}

String::~String() {
	delete p;

void String::print() {
