80年不写C++, 今天遇到 类 "xxx" 不存在默认构造函数
我都忘了怎么解决…
customer.h
文件:
#ifndef CUSTOM_H
#define CUSTOM_H
#include<string>
class Customer{
public:
Customer(std::string name, int age);
// virtual ~Customer();
void printInfo() const;
private:
std::string m_strName;
int m_iAge;
};
#endif
customer.cpp
文件:
#include <iostream>
#include "customer.h"
using namespace std;
Customer::Customer(string name, int age){
m_strName = name;
m_iAge = age;
}
void Customer::printInfo() const{
cout << "name: " << m_strName << endl;
cout << "age : " << m_iAge << endl;
cout << endl;
}
代码报错位置
m_xxxx = new Customer[12]; // 堆申请内存(可能会失败)
报错:
类 "Customer" 不存在默认构造函数
给他传入一个默认值就好了,在 customer.h
文件中修改:
Customer(std::string name="", int age=-1);
