如何使用数组获取输入，并将其存储在record.h类的主类中的变量中
How can I get input using an array and store in the variable in my main class from my record.h class?
如何获取输入并将其存储到Record.h文件中定义的每个变量中？
我试图用一个数组来简化它，但我不知道如何做到这一点。我已经想了好几个小时了。我甚至不确定这是否可能。
这是我正在进行的任务，以了解
对于此活动，您将创建一个地址簿控制台程序那个1.在主程序中使用一个基本数组来保存多个Record类对象。2.Record类将由以下成员变量构造：Record number、名字、姓氏、年龄和电话号码。
3.Record类必须具有初始化成员变量的自定义构造函数。
4.Record类声明将与Record类实现分离，这些声明将放在.h和.cpp文件中分别地
5.程序应该有一个永久菜单，允许选择：
a。将信息输入到记录中，(这是我的问题)
b。显示所有记录中的所有信息，以及
c。退出程序。
6.程序至少应保存10条记录。
7.在提交此作业的.cpp和.h文件之前，使用0人输入、5人输入和10人输入测试输出。

我在main.cpp中尝试过的代码没有特定的顺序

Record Employee10("Ab1232","Jake","Jones","205-612-5519","30");
Record Item[10];
for (int i = 0; i < 10; i++)
{
Item[i].setemployeeID("NA");
}
for (int i = 0; i < 10; i++)
{

就我理解的问题而言，你可以这样做：
Main.cpp
#include <iostream>
#include "Record.h"
#define RECORD_SIZE 10
using namespace std;
int main()
{
int choice;
Record items[RECORD_SIZE];
do {
cout << "Menun";
cout << "1.Input information into an record.n";
cout << "2.Display all information in all records.n";
cout << "3.Exit the programn";
cout << "Please enter your choice:n";
cin >> choice;
switch (choice) {
case 1: {
std::string fnameIN, lnameIN, idIN, telephoneIN, ageIN;
for (int i = 0; i < RECORD_SIZE; i++) {
cout << "Enter Employee ID:n";
cin >> idIN;
cout << "Enter Employee's First Name:n";
cin >> fnameIN;
cout << "Enter Employee's Last Name:'n";
cin >> lnameIN;
cout << "Enter Employee's Phone Number':n";
cin >> telephoneIN;
cout << "Enter Employee's Age:n";
cin >> ageIN;
items[i].setemployeeID(idIN);
items[i].setfirstName(fnameIN);
items[i].setlastName(lnameIN);
items[i].settelephone(telephoneIN);
items[i].setage(ageIN);
}
break;
}
case 2: {
for (int i = 0; i < RECORD_SIZE; i++) {
cout << "Employee " << (i + 1) << " details: n"
<< items[i].getemployeeID() << "n"
<< items[i].getfirstName() << "n"
<< items[i].getlastName() << "n"
<< items[i].gettelephone() << "n"
<< items[i].getage() << "n";
}
getchar();
break;
}
case 3: {
break;
}
default: {
cout << "Invalid Choice entered!";
}
}
} while (choice != 3);
return 0;
}
建议：
1) 在Record类中，可以将getter函数设置为const。像这样：
string getfirstName() const;
2) 在这种情况下，您可以使用默认参数，而不是定义单独的构造函数。你可以这样做：
记录.h
#ifndef Record_h
#define Record_h
#include <string>
using namespace std;
class Record
{
private:
string employeeID;
string firstName;
string lastName;
string telephone;
string age;
public:
explicit Record(string idIn = "NA", string fnameIn = "NA", string lnameIn = "NA",
string telephoneIn = "NA", string ageIn = "NA") {
setemployeeID(idIn);
setfirstName(fnameIn);
setlastName(lnameIn);
settelephone(telephoneIn);
setage(ageIn);
}
void setemployeeID (string idIn);
void setfirstName (string fnameIn);
void setlastName (string lnameIn);
void settelephone (string phoneIn);
void setage (string ageIn);
string getemployeeID() const;
string getfirstName() const;
string getlastName() const;
string gettelephone() const;
string getage() const;
};
#endif /* Record_hpp */
3) 对于验证，请始终使用setter。
记录.cpp
#include "Record.h"
void Record::setemployeeID (string idIn) {
employeeID = idIn;
}
void Record::setfirstName (string fnameIn) {
firstName = fnameIn;
}
void Record::setlastName (string lnameIn) {
lastName = lnameIn;
}
void Record::settelephone (string phoneIn) {
// TODO: I would highly recommend you to do this using REGEX
if (phoneIn.length() == 12
&& phoneIn.at(3) == '-'
&& phoneIn.at(7) == '-') {
telephone = phoneIn;
} else {
telephone = "000-000-0000";
}
}
void Record::setage (string ageIn) {
age = ageIn;
}
//get functions
string Record::getemployeeID() const {
return employeeID;
}
string Record::getfirstName() const {
return firstName;
}
string Record::getlastName() const {
return lastName;
}
string Record::gettelephone() const {
return telephone;
}
string Record::getage() const {
return age;
}
4) 正如我在代码中提到的，您应该用涉及RegEx的替代方案来替换telephone相关的验证。
5) 对方法名称使用标准命名约定。
