So yeah

I've gotten my first assignment and I'm starting it early. We're creating a Car rental menu, I was gonna use dictionaries since I'm used to Python and Luau then I found out C++ doesn't have dictionaries, it has maps

[stark locust]

This is a classic.

So because of how C++ overloading works, it will look at the argument type, then try to look for a matching overload. If it fails with a match, you don't get a "you should use type X, you used Y", but this error instead.

In this case you have to look at what it expects for insert (which is non-trivial for templated code):

https://cplusplus.com/reference/map/map/insert/

An example gives: mymap.insert ( std::pair<char,int>('a',100) );

So in your case you need to pass: std::pair<string, bool>("foo", true) or something like that.

If you want to use it in a more sane way, use emplace to infer the std::pair for you:

mymap.emplace("foo", true);

Alright so I've given it a quick read through but another issue has popped up

[rigid pond]

I'll pin this somewhere, thanks for that

if (pcEntry == passcode) {
        cout << "Good day Stock Manager!" << endl;
        cout << "Please enter the car model:" << endl;
        cin >> value1;
        cout << "Please enter the rental status: true or false (case sensitive):" << endl;
        cin >> value1;
        
        carlist.emplace(value1,value2);
    }

Pretty much all I changed in the entire thing

I did a little looking on stackoverflow for the operator thing but none of it makes any sense

[hot wyvern]

@rigid pond Has your question been resolved? If so, run !solved :)

[stark locust]

What is your “value2”?

[rigid pond]

value2 is a bool

[stark locust]

Do you have the full code?

[rigid pond]

Yeah gimmie a moment

#include <iostream>
#include <map>

using namespace std;
int passcode = 876;
int pcEntry;
bool pcComplete = false;
string mapEntry;
string value1;
bool value2;

map <string, bool> carlist;


// We create a function to post the car menu
void carMenu();


//  We create a function that checks if the correct code is put in, will be needed for later
int checkPasscode(bool) {

    // If the pcComplete is false, we run this code allowing the Manager to input the passcode for adding cars
    if (pcComplete == false) {

            cout<< "Please enter the manager passcode:" << endl;
            cin >> pcEntry;
            cout<< pcEntry << endl << endl;
                
    }

    if (pcEntry == passcode) {
        cout << "Good day Stock Manager!" << endl;
        cout << "Please enter the car model:" << endl;
        cin >> value1;
        cout << "Please enter the rental status: true or false (case sensitive):" << endl;
        cin >> value1;
        
        carlist.emplace(value1,value2);
    }

    return pcComplete;
}

// The main function
int main() {
    checkPasscode(pcComplete);
    return 0;
}

[stark locust]

What compiler? This compiles with Clang and GCC

[rigid pond]

GCC

[stark locust]

What version?

[rigid pond]

Actually

it's mingw, version is 13.2.0

[stark locust]

Works on 14.x

With Clang

If that was what you were testing.

Also works on msvc

[rigid pond]

I'll check that out at school today

I restarted vsc and it works now

[stark locust]

👍

[rigid pond]

gonna revisit that link u sent me before and check how to output it now

Thanks for the assistance

!solved

[hot wyvern]

Thank you and let us know if you have any more questions!

This thread is now set to auto-hide after an hour of inactivity

[wispy gull]

cout << "Please enter the car model:" << endl;
cin >> value1;
cout << "Please enter the rental status: true or false (case sensitive):" << endl;
cin >> value1;

Did you mean to stream to value1 on both statements?

To my untrained eye, the second instance should be to a temp string, which is subsequently compared with either "true" or "false".

[rigid pond]

No I didn't mean to, thanks for that

I'll try give that a go also

[silver plank]

Btw @rigid pond you are in C help, head over to #1013107104678162544 next time

[rigid pond]

Ohhh
