using System;
namespace ConsoleApp2
{
class Program
{
static void DispMenu()
{
Console.WriteLine("[1] Start\n[2] Instructions");
Console.Write("Enter your choice: ");
}

{
Random numberGenerator = new Random();
int PCount = 0;
int QCount = 0;
int iScore = 0;
int iCount = 0;
int iChoice;

while (iCount == 0)
{
DispMenu();
iChoice = int.Parse(Console.ReadLine());

if (iChoice == 1)
{
Console.WriteLine("Press enter to start the game...");
Console.ReadLine();
iCount = 1;
}
else
{
Console.WriteLine("Just take your time and try to do it.");
}

}

while (QCount < 10)
{
int RandNum1 = numberGenerator.Next(1, 11);
int RandNum2 = numberGenerator.Next(1, 11);
Console.WriteLine("" + RandNum1 + " * " + RandNum2 + "");
Console.WriteLine();

Console.WriteLine();
