    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.

    You probably want choice to be a char instead of an int.

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.

    You are mixing up \ and / some of the time. Other than that, when you press 5, what do you do next? Hit enter. It's in the FAQ.

    Hope is the first step on the road to disappointment.
