Answer 1

To do what you want you can do this:

#include <iostream>
#include <string>

using namespace std;

int main()
{
   int x;
   char chars = '*';
   cin >> x;

   for (int i=1; i<=x; i++){
       cout << chars;
  }

    cout << "\n\n";
    system("pause");
    return 0;
}

Answer 2

As stated in comments - char when multiplied by int results in int .

Is below code what you wanted?

#include <iostream>

int main()
{
  int x;
  char const chars = '*';
  std::cin >> x;

  for (int i=1; i<=x; i++) std::cout << chars << std::endl;
  return 0;
}
