How to store a score?

[DecoratorFawn82]

Hey there! I'm wonder of how to store a score I am doing a question game and needs to store coins for every question the user enters the correct answer. I want to do something like when you have completed the first question then the program will give you +3 in coins then you have completed next question then I want the program to add 3 more so it says you have a value of coins 6. But I do not know exactly how to do this the code I begun to write was this:

#include <iostream>

using namespace std;

int main()
{
int answer;
int coins = 3;

//Have no questions yet if you wonder
cout << "Question1";
cin >> answer;

if (answer == 1)
{
   cout << "Correct!" << coins;
}
else if (answer != 1)
{
   cout << "Wrong!";
}
return 0;
}

This code works for 1 question but I want it to work like add 3 for every question the user guesses correct. Like if user enters the correct answer 3 times then he/she has a value of coins 9.

You already have a coin variable in your program. I would suggest you use that. Initialize it to 0 to begin with. Each time the user gets the correct answer just increment that value by 3 ( coin += 3; ).

On a side not, you could have just used an else instead of else if in your code sample above.

if (answer == 1)
{
    coin += 3;
    cout << "Correct!  You now have " << coins << " coins.";
}
else
{
   cout << "Wrong!";
}

You can use a counter. It's very simple. Initialize it at 0 and add 3 everytime the user answers correctly,

Example:

#include <iostream>


int main()
{
    int answer;
    int coins_obtained = 0; //You initialize the counter


    std::cout<<"How much is 1+1?" <<std::endl <<std::endl;
    std::cin >> answer;
    std::cout<<std::endl;


    if (answer == 2)
    {
        std::cout<<"Correct!" <<std::endl <<std::endl;
        coins_obtained = coins_obtained + 1;  //Adds 1 to the previous value of coins
        std::cout<<"You own " <<coins_obtained <<" coin(s) at this point.";
    }
    else
    {
        std::cout<<"Wrong Answer!" <<std::endl <<std::endl;
        coins_obtained = coins_obtained; //Same number of coins - This step is not required, only added it so you understand it better
        std::cout<<"You own " <<coins_obtained <<" coin(s) at this point. ";
    }


    std::cin.ignore();
    std::cin.get();
}
