Error. C++. Expected primary-expression before ')' token

Question

I wrote a simple program and met an error in switch . What is wrong?

Error: expected primary-expression before ')' token

#include <iostream>
#include <list>
using namespace std;

int main() {
    list<string> myList;

    string s;
    while (true) {
        cin >> s;
        switch(s) {
            case "quit":
            break;

            default:
            myList.push_back(s);
            break;
        }
    }
}

Thanks.

Answer 1

The real problem is here:

 switch(s) {

You cannot use strings in a switch case.

Alternative:

An if-else ladder. Since you have only one case, use an if statement for it. For example:

if (s=="quit") {
    break;
} 
else 
    myList.push_back(s);
