Program closes prematurely. Help needed

I'm a beginner in C++, so this might be considered an elementary problem, but bare with me. The program is just supposed to create a class that's used to compute the volume of a cube. It asks for the three dimensions, but then closes. Here's the code....

Code:

using namespace std;

class Volume {
      
      public:
             int x, y, z;
          void set_dimensions(){
               int a, b, c;
               cout << "Enter the length: ";
               cin >> a;
               cout << endl << "Enter the width: ";
               cin >> b;
               cout << endl << "Enter the height: ";
               cin >> c;
               cout << endl;
                                x = a;
                                y = b;
                                z = c; }
          int volume() {return (x*y*z); }
      };
      
      int main(){
          Volume cube1;
          cube1.set_dimensions();
          cout << "The volume of the cube is: " << cube1.volume();
          cin.get();
          return 0;
          }

Thanks for the help.

try add a cin.ignore() right before cin.get()

Those FAQs don't help much in this case.
