Random number in output of my C++ file

[yoshi445511]

just trying to get used to classes.
Whenever i run the program, it works fine, except for a random number that pops up.

source:

#include <iostream>
using namespace std;
 
class CRectangle
    {
    public:
    int x, y;
    int area()
        {
        int a = x*y;
        cout << a << "\n";
        }
    };
int main()
{
    CRectangle area;
    cout << "What is the length: ";
    cin >> area.x;
    cout << "What is the width: ";
    cin >> area.y;
    cout << area.area() << "\n";
    return 0;
}

output:

What is the length: 9
What is the width: 97256
875304
134521056
 

any ideas?

Your function area doesn't return the value, so some random number is inserted by the compiler and printed by cout << area.area() << "\n";

Missing that return should have caused a compile time error. Did you not get one?
