Answer 2

#include <iostream>
#include <vector>
using namespace std;

void square(int height, int width, char symbol){
for (int h = 0; h< height; h++)
{
for (int w =0; w< width; w++){
cout << symbol << " ";
}
cout<<endl;
}

}
int main()
{

// cout << " Height " ;
// cin >> height;
// cout << " Width";
// cin >> width;
// cout << "symbol";
// cin >> symbol;
square(5,6,'+'); //pass only matched type values, if you passing "+" then use string symbol in defination
//square(5,7,"+"); then use function like void square(int height, int width, string symbol){ ...} And it returning nothing so nothing to display by cout<<square(5,7,'+') ,remove cout. Just call function.

return 0;
}
