Question

Hi I am using Repl.it, could anyone help fix the errors?

Instruction:

main.cpp

The code I have given you is correct. The problem is that the #include statements are missing. You need to examine the error message you get and put the correct #include statements in the files. HINT: If there is an error that some type is not found, and you that type exists, it's a #include error. All three files are missing #include statements.

#include <iostream>
#include <cstdlib>
#include "InvItem.h"
using namespace std;

int main() {
InvItem a;
string description, idNumber;
  
// read in two strings
getline(cin, description);
getline(cin, idNumber);
  
// store properties in the object
a.setDescription(description);
a.setIDNumber(idNumber);
  
// print out the properties of the object
cout << a.getDescription() << endl;
cout << a.getIDNumber() << endl;
  
}

--------------​​​​​​​-------​​​​​​​-------​​​​​​​-------​​​​​​​-------​​​​​​​-------​​​​​​​-------​​​​​​​-------

invltem.h

#ifndef INVITEM_H
#define INVITEM_H
#include<string>
using std::string;

class InvItem
{
public:
InvItem();
void setDescription(string desc);
void setIDNumber(string id);
  
string getDescription() const;
string getIDNumber() const;
private:
string desc;
string id;
};

#endif

-------​​​​​​​-------​​​​​​​-------​​​​​​​-------​​​​​​​-------​​​​​​​-------​​​​​​​-------​​​​​​​-------​​​​​​​-------

invltem.cpp

#include "InvItem.h"
#include<string>
using std::string;

InvItem::InvItem(): desc(""), id(""){}
void InvItem::setDescription(string desc){
this->desc =desc;
}
void InvItem::setIDNumber(string id){
this->id=id;
}

string InvItem::getDescription() const{return desc;}
string InvItem::getIDNumber() const{return id;}

Answer 1

Dear student your code is correct but only one small mistake you have made.

Your mistake is the filename in #include statement.

Your header file name is invltem.h but in you code you have written #include "Invltem.h" (the I should be lowercase)

Change your include line to #include "invltem.h" in both files

Please do the above change in include statements and try running your code.

If you face any more errors then let me know in comment section.
