Simple survey

[PHDpaul]

I have an assignment for class that I can't figure out how to start. I'm supposed to create a survey that records a number of peoples drink choices and tells the user how many times each drink was selected out of the menu at the end. I tried to start it but i hit a wall.

#include <iostream>
using namespace std;
int main()
{
    //Variables defined for drink choices
    const int COFFEE = 1,
              TEA = 2,
              COKE= 3,
              OJ = 4;
            int exit;
            int people;
            int num;
            int choice;

            //Menu for Choices
            cout<<"How many people will be taking this survey?\n";
            cin>>people;

            for (num =0; num<people;num++)
            cout<<"Favorite Beverage Choices\n1.Coffee\n2.Tea\n3.Coke\n4.OJ\n-1 to exit the program\n\n";


              cout<<"Please input favorite beverage of person #"<<num<<endl;
              cout<< "Press 1,2,3, or 4 from the above menu. Press -1 to exit.\n";
              cin>>choice;




    return 0;
}

any ideas?

i forgot to add the sample output that was provided

Please input the favorite beverage of person #1: Ch
oose 1, 2, 3, or 4 from the
above menu or -1 to exit the program
4
Please input the favorite beverage of person #2: Ch
oose 1, 2, 3, or 4 from the
above menu or -1 to exit the program
1
Please input the favorite beverage of person #3: Ch
oose 1, 2, 3, or 4 from the
above menu or -1 to exit the program
3

Please input the favorite beverage of person #4: Ch
oose 1, 2, 3, or 4 from the
above menu or -1 to exit the program
1
Please input the favorite beverage of person #5: Ch
oose 1, 2, 3, or 4 from the
above menu or -1 to exit the program
1
Please input the favorite beverage of person #6: Ch
oose 1, 2, 3, or 4 from the
above menu or -1 to exit the program
-1
The total number of people surveyed is 5. The resul
ts are as follows:
Beverage Number of Votes
********************************
Coffee 3
Tea 0
Coke 1
Orange Juice 1

Start with a flowchart or pseudo code. Post that and let's look at translating it to real code.

I came up with a pseudo code but i couldn't figure out how to start i dove in. This is my first programming class. I came up with a rough draft but it won't keep track of the answers given

#include <iostream>
using namespace std;
int main()
{
    //Variables defined for drink choices
     int COFFEE = 0,
              TEA = 0,
              COKE= 0,
              OJ = 0;
            int exit;
            int people;
            int num=1;
            int choice;
            int totalC=0,
                totalT=0,
                totalCk=0,
                totalO=0;

            //finding the number of time the questions will be asked
            cout<<"How many people will be taking this survey?\n";
            cin>>people;
            //menu for beverage choices 
            while(num<=people)
            {
            cout<<"Favorite Beverage Choices\n1.Coffee\n2.Tea\n3.Coke\n4.OJ\n-1 to exit the program\n\n";

              cout<<"Please input favorite beverage of person #"<<num<<endl;
              cout<< "Press 1,2,3, or 4 from the above menu. Press -1 to exit.\n\n";
              cin>>choice;
              num++;
            }
//switch to tally up the choices to be displayed at the end
switch(choice)
{
    case '1': (totalC++);
        break;
    case'2': (totalT++);
        break;
    case'3': (totalCk++);
        break;
    case '4': (totalO++);
        break;
    default: cout<< "Invalid selection\n";
        break;
}
//display of total picks
cout<<"The number of people surveyed is "<<people<<".\n\n";
cout<<"Beverage Vote List\n";
cout<<"*********************************\n";
cout<<"Coffee:"<<totalC<<endl;
cout<<"Tea:"<<totalT<<endl;
cout<<"Coke:"<<totalCk<<endl;
cout<<"Orange Juice:"<<totalO<<endl;


    return 0;
}

That's why you need pseudo code.
Ignore the programming language for now.
Think about, if you were given this task in real life, how you would accomplish it in small logical steps. Then write those down.

[PHDpaul]

ok i guess i'd first find out how many people need to be surveyed. I'd then show my question to someone and record their response, and repeat that until i had asked everyone and gotten their answers. Then i'd tally them up and display them

[Elysia]

Right. That's a good start. But also consider that judging from the output above, it doesn't say that you know how many will be surveyed, so keep that in mind.
Now, the next step after amending your approach to the fact above, is to break it down into more logical steps. Computers are stupid, and we need to guide them.
How do you show a question to someone?
How do you record their response?
How do you tally up the answers?
How do you display them?
We're not talking about just one person here, we're talking about many. So try to break it up into smaller steps by taking that into account.

For example, given a task to count the number of sheep, I might

For every sheep
Increment the number of sheeps by one
Loop
Print the total number of sheeps

[PHDpaul]

hmmmmm ok i see what you're saying now. So i'd ask for the number of people, input that number, set the question to loop 'x' number of times, everytime a beverage is selected it would increment by one until the loop is completed, and i'd cout the variables after they'd been incremented.

[PHDpaul]

wow i just got it to work. definitely just had to take the steps through one by one. Thanks man, i had been working on this for hours

[Elysia]

Good work. If you get stuck, remember these basic exercises!
