Answer 1

#include <iostream>

using namespace std;

void displaySquare(int rows, int cols, char fillCharacter) {
	for (int i = 0; i < rows; ++i) {
		for (int j = 0; j < cols; ++j) {
			cout << fillCharacter;
			if (j == cols - 1) cout << "\n";
			else cout << " ";
		}
	}
}
int main() {
	int rows, cols;
	char c;
	cout << "Enter a character to fill the rectangle: ";
	cin >> c;
	cout << "Enter sides: ";
	cin >> rows >> cols;
	displaySquare(rows, cols, c);
	return 0;
