1.1 Pass-by-reference Assignment

For this part of the lab (lab3a), we are going to pretend that we are on a text-based adventure game. Our life will be measured via hit points and we start with 10 hit points. If we want to increase our hit points, we can quaff a potion using the command quaff potion and it will increase our hit points by 2.

·        Ask the user what they would like to do. Have the user enter quaff potion using two words. As a reminder, you will have to use getline because it is two words. You can use a string or a c-string.

·       Using pass-by-reference, create a void function called quaff that adds two hit points.

·       In main, display the original hit points (10) and new hit points after quaffing the potion (12)

Here is an example execution of the program:

--bash-4.1$ ./lab3a

You have 10 hit points.

What would you like to do?:

quaff potion

You have quaffed the potion!

You have 12 hit points.

-bash-4.1$

--bash-4.1$ ./lab3a

You have 10 hit points.

What would you like to do?:

quaff potion

You have quaffed the potion!

You have 12 hit points.

-bash-4.1$

Explanation / Answer

#include <iostream>
using namespace std;
void quaff (int &hitPoints){
hitPoints = hitPoints + 2;
}
int main() {
   int hitPoints = 10;
   string line;
   cout<<"You have "<<hitPoints<<" hit points."<<endl;
   cout<<"What would you like to do?:"<<endl;
   getline(cin, line);
   quaff(hitPoints);
   cout<<"You have quaffed the potion!"<<endl;
   cout<<"You have "<<hitPoints<<" hit points."<<endl;
   return 0;
}

Output:

You have 10 hit points.
What would you like to do?:

quaff potion
You have quaffed the potion!
You have 12 hit points.
