7. Enter month-date to see if the format is correct. Take advantage of DateTime.
2013-2-2 2013/2/2
Try Catch finally
Console.WriteLine ("Please enter Date:");
Try
{
DateTime time1 = DateTime.Parse (Console.ReadLine ());
Console.WriteLine ("The format you entered is correct!") ");
}
Catch
{
Console.WriteLine ("The format you entered is not correct!") ");
}
Finally
{
Console.WriteLine ("Thank you for your use!") ");
}
Console.ReadLine ();

8. Machine scissors, scissors stone cloth. Use switch case.
Stochastic, Random. Next (1,3)
Random a = new random ();
A game of victory
Console.WriteLine ("What is the stone scissors cloth out of");
String a = Console.ReadLine ();
int b = 0;
Switch (a)
{
Case "stone":
b = 1;
Break
Case "Scissors":
b = 2;
Break
Case "cloth":
b = 3;
Break
}

Random x = new Random ();
int y = 0;
int z = 0;
y = X.next (1,3);
Switch (y)
{
Case 1:
Console.WriteLine ("Stone");
Break
Case 2:
Console.WriteLine ("Scissors");
Break
Case 3:
Console.WriteLine ("Cloth");
Break
}
z = y-b;
Switch (z)
{
Case 0:
Console.WriteLine ("Tie");
Break
Case-2:
Console.WriteLine ("won");
Break
Case-1:
Console.WriteLine ("Lost");
Break
Case 1:
Console.WriteLine ("won");
Break
Case 2:
Console.WriteLine ("Lost");
Break
}

9. Enter a positive integer, and ask for 1! +2! +3! +...+n!. Nesting with for loops.
Console.Write ("Please enter a positive integer:");
int a = Int. Parse (Console.ReadLine ());
int sum = 0;
for (int i = 1; i <= A; i++)
{
int jie = 1;
for (int j = 1; J <= I; j + +)
{
Jie *= J;
}
sum + = Jie;
}
Console.Write (sum);
Console.ReadLine ();

10. Find the number within 100 and 7 related and print and find out their and. Use the For loop +if.
7 is single-digit a%10==7
7 is a 10-digit a/10==7
Multiples of 7 a%7==0
int sum = 0;
for (int a = 1; a <=; a++)
{
if (a% = = 7 | | a/10 = = 7 | | A% 7 = = 0)
{
Console.WriteLine (a);
sum + = A;
}
}
Console.WriteLine (sum);
Console.ReadLine ();
