Resize a square

[pieterdehoogd]

Hey, In a part of my programm I want to resize a square.
This is my code:

const int MAX = 50;

class square {
public:
   square();
   void print();
private:
   int height, width;
};

square::square(void) {
print();
}

void square::print() {
   int i, j;
   for(i=1; i<MAX; i++) {
      for(j=1; j<=MAX; j++) {
         if(i==1 || i==MAX || j==1 || j==MAX) {
            cout << "+";
         }
         else {
            cout << " ";
         }
     }   
     cout "\n";
   }
}

In the constructor square() I want to resize the height and width of the square to (for example) 20. How do I do that?

You don't seem to be setting height/width anywhere? Why use MAX? Shouldn't you be using height/width here? But as this is a square and not a rectangle, why 2 sizes and not 1?

include <iostream>
using namespace std;

class square {
public:
	square() {};
	square(int s);
	void print() const;
	void resize(int s);
private:
	int size {5};
};

square::square(int s) : size(s) {}

void square::resize(int s)
{
	size = s;
}

void square::print() const {
	for (int i = 1; i <= size; i++) {
		for (int j = 1; j <= size; j++) {
			if (i == 1 || i == size || j == 1 || j == size) {
				cout << "+";
			} else {
				cout << " ";
			}
		}
		cout << "\n";
	}
}

int main()
{
	square s(5);
	s.print();

	s.resize(20);
	s.print();
}
