I am stuck and mega confused

awkitup (4)
I am trying to write a program that uses a user defined function. It will prompt the user to enter a valid height and valid width. After these two numbers are validated, it will then print a row of x's ( with height being how many rows pring, and with being the number of x's within each row.)

For example:
Height: 3
width: 6

output:
xxxxxx
xxxxxx
xxxxxx

  #include <iostream>

using namespace std;

void box(int);

int main()
{
	int h, w;
	box(2);

	cout << "Enter height (0-25): " << endl;
		cin >> h;

	cout << "Enter width (0-25): " << endl;
		cin >> w;

		if (h < 0 || h > 25 || w < 0 || w > 25){
			cout << "invalid number";
			cout << "Please enter a number between 0 and 25: " << endl;
		}

		else if  (h > 0 && h < 25 && w > 0 && w < 25){
			for (int x = 1; x <= h; x += h) {
				cout << "X" << x << endl;
			}
			for (int y = 1; y <= w; y += w) {
				cout << "X" << y << endl;
			}
				

			}

		else if(){
			cout << "Please enter a number between 0 and 25: " << endl;
		}

		cout << "Exiting..." << endl;
		return 0;
		
}

The for loops on 24 and 27 are all kinds of messed up. Try and work out the logic of what they're doing.

Line 34 should be else {

for (int x = 1; x <= h; x ++)
		{
			{
				for (int y = 1; y <= w; y ++)
				cout << "X" ;
		        }
				cout << endl;

delete the reference to box[2]

Try starting with getting it running properly without the error checking else's and if's and maybe use a while statement once you solve the X's displaying properly.
