Thread: unknown problem!

I am writing a program to calculate the area of shapes i've hit a problem everytime i run the program and input my choice it prints the start again-

Code:

#include <iostream>
using namespace std;

int main(){
    int choice, w, l;
    do{
       cout << "Find the Area\n";
       cout << "Please enter number of choice(q for quit): \n";
       cout << "1. Square\n";
       cout << "2. Rectangle\n";
       cout << "3. Triangle\n";
       cout << "4. Circle\n";
       cout << "5. Cube\n";
       cin >> choice;
       } while ( choice < '1' || choice > '5' && choice != 'q' );
       
       if (choice == 'q') exit(1);
       
       switch (choice){
              case '1':
                   cout << "\nEnter the width: ";
                   cin >> w;
                   cout << "\nArea is: " << w*w << "cm2";
              case '2':
                   cout << "\nEnter the width: ";
                   cin >> w;
                   cout << "\nEnter the length: ";
                   cin >> l;
                   cout << "\nArea is: " << w*l << "cm2";
              case '3':
                   cout << "\nEnter the width: ";
                   cin >> w;
                   cout << "\nEnter the height: ";
                   cin >> l;
                   cout << "\nArea is: " << 2/(w*l) << "cm2";
              case '4':
                   cout << "\nEnter the radius: ";
                   cin >> w;
                   cout << "\nArea is: " << 3.14*(w*w) << "cm2";
              case '5':
                   cout << "/nEnter the height: ";
                   cin >> l;
                   cout << "/nArea is: " << l*l*l << "cm3";
                   }
              return 0;
              }

Thanks for any help, it is much appreciated.
