Question

You need to write two simple getter methods in order to access the size and allocSize class member values. These should be called getOne() and getTwo() respectively. These functions should be class const functions (you guarantee that calling them will not cause the class to be modified. These functions take no parameters as input. They both return an int value, because the size and allocSize member parameters are both integer values.

#include <iostream>
using namespace std;

class Sizes {
private:
    int size;
    int allocSize;
public:
    Sizes(int size, int allocSize) : size(size), allocSize(allocSize) {}

    int getOne() const {
        return size;
    }

    int getTwo() const {
        return allocSize;
    }
};

int main() {
    Sizes sizes(2, 7);
    cout << sizes.getOne() << endl;
    cout << sizes.getTwo() << endl;
    return 0;
}
