    Question Newbie please help me

    Hi,

    Please tell me what I am doing wrong.When I press A,B,C it just doesnt enter into switch case.why??
    OUtput on the screen is "incorrct productcode entered.total is 0"

    Actually,I want to find the total sales for entire week so should I put in while loop and keep counter 7 ???

    Thankx in advance.
    #include<iostream>

    using std::cout;
    using std::cin;
    using std::endl;
    int main()
    {
    int ans,qty,counter;
    double prdA,prdB, prdC,saleA,saleB,saleC,total;
    saleA=0,saleB=0,saleC=0,total=0;
    prdA=2.98;
    prdB=4.50;
    prdC = 9.98;
    counter=0;

    cout<<"enter the product A-C "<<endl;
    cin>>ans;


    switch(ans)
    {
    case 'A':
    case 'a':
    {
    cout<<"enter qty"<<endl;
    cin>>qty;
    saleA=prdA*qty;
    cout<<"ur sale is"<<saleA<<endl;
    break;
    }

    case 'B':
    case 'b':
    {
    cout<<"enter qty"<<endl;
    cin>>qty;
    saleB=prdB*qty;
    cout<<"ur sale is"<<saleB<<endl;
    break;
    }
    case 'C':
    case 'c':
    {
    cout<<"enter qty"<<endl;
    cin>>qty;
    saleC=prdC*qty;
    cout<<"ur sale is"<<saleC<<endl;;
    break;
    }

    default:
    {
    cout<<"incorrect productcode entered"<<endl;
    break;
    }
    }


    total = saleA+saleB+saleC;
    cout<<"total is "<<total;
    return 0;
    }

    Please guide me.....

    You declare ans as an int and then compare it to things like 'A' and 'B'... Let's ponder this.

    Lightbulb Thankx But...

    Hi,
    thanks for pointing me out for such a silly mistake.I converted it into char.
    but my second query is now i want to find total sales for a entire week,so how to put it in while loop ?
    thanks once again.

    Smth like this:

    int count = 0;

    while(count <7)
    {
    do stuff
    count++;
    }

    Actually, if you're dealing with chars, I doubt you can do it with a loop without a lot conversion to int and enums. You should just go through a bunch of times with the += operator.
