C#
(Guess the Number Game) Write a program that plays “guess the number” as follows: Your program chooses the number to be guessed by selecting an int at random in the range 1–1000. The program then displays the following text in a label:
A TextBox should be used to input the guess. As each guess is input, the background color should change to red or blue. Red indicates that the user is getting “warmer,” blue that the user is getting “colder.” A Label should display either “Too High” or “Too Low,” to help the user zero in on the correct answer. When the user guesses the correct answer, display “Correct!” in a message box, change the Form’s background color to green and disable the TextBox. Recall that a TextBox (like other controls) can be disabled by setting the control’s Enabled property to false. Provide a Button that allows the user to play the game again. When the Button is clicked, generate a new random number, change the background to the default color and enable the TextBox.
Q1: (Palindrome number) Write a program that prompts the user to enter a three-digit integer and determines whether it is a palindrome number. A number is palindrome if it reads the same from right to left and from left to right.
Here is a sample run of this program:
Enter a three-digit integer: 121
121 is a palindrome
Enter a three-digit integer: 123
123 not a palindrome
Q5. (Find the second lowest interger number) Write a program that prompts the user to enter
a set of integer numbers, and finally displays the second lowest integer number in the set. To
exit from the program enter -1.
Here is a sample run
Enter a set of integer numbers: 3 57
928-1 The second lowest number is
