3 Campus Travel Game

This lab will practice using loops.

We will construct a short computer game. Please look at the Test Cases for exact wording.

For your game, the player’s goal is to reach campus exactly.

The player starts 14 miles away and has up to 4 turns to reach campus.

At each turn the play can ride either use a Bus, a Subway, or a Jetpack:

• Riding a Bus moves the player forward 2 miles each turn.
• Riding a Subway moves the player forward 5 miles each turn
• Riding a Jetpack moves the player forward 10 mile each turn.

Example:
You are 14 mile(s) from campus!
How do you wish to travel? (1 bus, 2 subway, 3 jetpack) 

The player chooses one.

After each turn, the player is informed how much farther she must travel before reaching campus.

Winning/Losing: After the last turn, if the player has reached campus exactly ("You have won!")

   Otherwise, explain the problem: "You have over-shot your target!" or "You haven't reached your target!"

   And then write “You lose!”

The game will operate as follows:

• Report how far the user is from campus – the player starts 14 mile away
• For each turn:

o Ask user to select transport method (Bus, Subway, or Jetpack)

o Report the user’s new distance from campus

o If the player has reached campus or passed campus and it is not the fourth turn, end the game early – This is a more challenging step! Make sure the rest of your game works before working on this step.

ALSO:

Check that the user input is valid (1-3).

If the user fails to pick a valid number, the program must keep asking the user for a new selection until a valid number is entered. ALSO- you do not lose turns by making an invalid selection.

    Use this wording:      Invalid choice, try again!

Requirements:

• You must use a loop (while, do-while, or for) to loop through the 4 turns. (The loop can include a condition to allow ending early, if you so choose.)
• You must use at least one if or switch statement
• Require the user enters one of three numbers to specify the transport method

Example Output:

You are 14 mile(s) from campus!

How do you wish to travel? (1 bus, 2 subway, 3 jetpack) 2

You are 9 mile(s) from campus!

How do you wish to travel? (1 bus, 2 subway, 3 jetpack) 1

You are 7 mile(s) from campus!

How do you wish to travel? (1 bus, 2 subway, 3 jetpack) 1

You are 5 mile(s) from campus!

How do you wish to travel? (1 bus, 2 subway, 3 jetpack) 2

You are 0 mile(s) from campus!

You have won!

Note : check attached image for output ,code compiled and tested in GCC code blocks ide.

Program :

#include<iostream>
using namespace std;

int main()
{
    int distance=14,i=0;//initial distance and loop count

    while(i<4) //loop till i<4
    {
        int choice; //user chocie
        cout<<"You are "<<distance<<" mile(s) from campus!"<<endl; //print current distance
        cout<<"How do you wish to travel? (1 bus, 2 subway, 3 jetpack) "; //prompt for input
        cin>>choice;
        switch(choice) //switch case
        {
            case 1: //if its bus choice
                distance-=2; //subtract 2 from distance
                i++; //increment loop count
                break;
            case 2: //its sub way choice
                distance-=5;//subtract 5 from distance
                i++;
                break;
            case 3: //its jetpack choice
                distance-=10; //subtract 10 from distance
                i++;
                break;
            default: //Invalid input
                cout<<" Invalid choice, try again!"<<endl;
                break;
        }

        if(i<=4 && distance==0) //if i==4 or i<4 but distance ==0 end game early
        {
            cout<<"You are 0 mile(s) from campus!"<<endl; //print 0 distance and won message and break from loop
            cout<<"You won!"<<endl;
            break;
        }
        else if(i<=4 && distance<0) //if we over shot target still did not came 4th target or 4th target
        {
            cout<<"You have over-shot your target!"<<endl; //print over shoot message
            cout<<"You lose!"<<endl;
            break;
        }
        else if(i==4 && distance>0) //if all four turn completed still far from target
        {
            cout<<"You are "<<distance<<" mile(s) from campus!"<<endl; //print loose message
            cout<<"You haven't reached your target!"<<endl;
            cout<<"You lose!"<<endl;
            break;
        }
    }

    return 0;
}
