You're breaking out of the while loops, not the case statement.

Try this instead.

switch(choice)
{
    case 1:
        cout << "What do you want to add: ";
        cin >> sum;
        while(0 < sum)
        {
            // ...
        }
        break;  // <---- break statement goes outside while loop!

    // ...
}

You need to enclose the contents of the switch statement in braces, e.g.

1

    switch(choice)
    {
    case 1:
        // Do stuff
        break;

    case 2:
        // Do stuff
        break;

    // etc
    }

still cant after i put if/else statement T.T

I have no idea what that means. Can you try and be a bit clearer? What is it that you still can't do? What if/else statement?

You say do stuff means this?

    if(totalsum<0){
        cout <<"What are you calculating?" << endl;
    }
    else{
        cout <<"The answer is "<< totalsum << endl;
    }
    break;

"Do stuff" means whatever it is that you want to happen in that particular case. I'm not writing the code for you - I'm demonstrating the correct syntax for a switch/case statement.

but how can i do stuff in it ??? add what inside, can help ??
MikeyBoy (5631)
You write code! You were doing it in the code you originally posted, so why are you having trouble understanding it now?
