Hi everyone, i have been learning C++ for a few months now and i decided to make a small text game, but i need some help figuring something out. here is my code:

now what i want to do is make the health and money go up but they are in a function and i dont know how to make them go up when your in a different function. also how do you make the health or money go up and down in more increments than 1? i know about health++ or money++ but what if i wanted to give the player $10 or -5 health?

You can use money += 10 and health -= 5
Ch1156 (1999)
It gives me this error:

C:\Users\Chay Hawk\Desktop\C++ Projects\C++\main.cpp||In function 'int main()':|
C:\Users\Chay Hawk\Desktop\C++ Projects\C++\main.cpp|10|error: invalid operands of types 'int' and '<unresolved overloaded function type>' to binary 'operator<<'|
||=== Build finished: 1 errors, 0 warnings ===|

Heres the code i just used to test it out:

// void function example
#include <iostream>
using namespace std;


int main ()
{
int money = 0;

cout << money +=10 << endl;
cout << money << endl;

return 0;
}


also do you know how i would access those integers from another function? because i have health and money in one function and i'll be subtracting and adding money from the main function:

//View Statistics
void Stats()
{

int health = 100;
int money = 0;

cout << "\n";
cout << "Pet Health: " << health << endl;
cout << "\n";
cout << "Money: "<< "$" << money << endl;
cout << "\n";

}

int main ()
{
int money = 0;
money += 10;

//cout << money +=10 << endl;
cout << money << endl;

return 0;
}


As for your second case, you need parameter passing in your Stats

E.g
void Stats(int &health, int &money) {
health -= 5;
money += 10;
......
}

Call it from main function like

int main() {
int health = 0;
int money = 0;
Stats(health,money);
//down here if you cout you will see the changed values in health and money
...
}

    if(FoodChoice == "A" || FoodChoice == "a"){
        money =-2;
    }

}




I wanted to be able to set prices for each piece of food, i dont want a set price for all of it. i'm totally lost and confused right now on what to do.
Ch1156 (1999)
Can someone help me solve my problem i really need to get this done.

let us assume:

10
11
12
 

void SetFoodPrice()
{
        // I am assuming that foodPrice is a global to the program
        // double foodPrice = 0.0;
        
        cout << "Please Enter a Food Price:" << endl;
        cin >> foodPrice;

        cout << "You entered: " << foodPrice << endl;
}



One thing through out your code I don't see any std::cin to read in any data.

The cin data is ther, i put it in getline(cin, string here); because i plan to output the typed in stuff to a text document which i already know how to do. For the money what i want it to do is this:

I want to set the price of the food lets say $2 for regular food i want it to subtract from the total amount of money the player has every time they buy it. the cost of the food and items will be pre set and the player will not be able to set the price for them. The food will all be different prices so the code needs to subtract accordingly, this is where im stumped, my entire code is at the top of the page if you need to look at all of it to help you.

also i cannot figure out how to access the money and health data as they are all in different functions.

yes I noticed that too.

Have you learned about scope and/or having a function return a value:

1

8
9
10
11
12

double SetFoodPrice()
{
        double foodPrice = 0.0;
        
        cout << "Please Enter a Food Price:" << endl;
        cin >> foodPrice;

        return foodPrice; 
}

int main()
{
       double foodPrice = SetFoodPrice();
       
        cout << "You entered: " << foodPrice << endl;

       return 0;
}


You also had things with references in them function definition.

// your function :
void Stats(int &health, int &money);
{
      health += 10; // added 10 health
      money -= 2; // deducted 2 money
}

int main()
{
        int health = 10;
        int money = 10;

        Stat(health, money);

       // when you get here and print out the numbers you will note that they have changed.
        cout << "You have " << health << " health." << endl;
        cout << "You have $" << money << " left."  << endl;

        return 0;
}


This is two ways I can pass variables back and forth.

I cant remember but im pretty sure i didnt. I get an error

C:\Users\Chay Hawk\Desktop\TextPet\main.cpp||In function 'int main()':|
C:\Users\Chay Hawk\Desktop\TextPet\main.cpp|73|error: too few arguments to function 'void Stats(int&, int&)'|

//View Statistics
void Stats(int &health, int &money)
{
    health += 10;
    money +=10;


    cout << "\n";
    cout << "Pet Health: " << health << endl;
    cout << "\n";
    cout << "Money: "<< "$" << money << endl;
    cout << "\n";

}


what i want it to do is deduct the amount i pre set in code when the user selects which type of food they want. so in this code:

1
2
3

void FeedTextPet()
{
    string FoodChoice;

    cout << "What would you like to feed your TextPet?" << endl;
    cout << "\n";
    cout << "A - TextPet " << endl;
    cout << "     " << "Cost: $2" << endl;
    cout << "     " << "     " << "Health Restored: 8 points" << endl;
    cout << "\n";
    cout << "B - " << endl;

    if(FoodChoice == "A" || FoodChoice == "a"){

    }

}


if the player chooses food A it will deduct $2 from their overall money. i was thinking it would work if in the if statement it would deduct it something like this:

if(FoodChoice == "A" || FoodChoice == "a"){
money -=2;
}

it is the function call in main:

1
2
3
4
5
6
7
8
9
10
 

// you have something like this which is wrong
int health = 10;
int money = 10;

Stats(); // this is where the error is.

// it should look like:
Stats(health, money);


for this I would expect:

    cout << "\n";
    cout << "A - TextPet " << endl;
    cout << "     " << "Cost: $2" << endl;
    cout << "     " << "     " << "Health Restored: 8 points" << endl;
    cout << "\n";

    if(FoodChoice == "A" || FoodChoice == "a")
    {
          health+=8;
          money-=2;
    }

}
