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
(Algebra: solve 2 x 2 linear equations) You can use Cramer's rule to solve the
following 2 X 2 system of linear equation:
ed – bf
ax + by = e
cx + dy = f
af - eс
y
ad – bc
%3D
ad – bc
Write a program that prompts the user to enter a, b, c, d, e, and f, and displays the
result. If ad – bc is 0, report that "The equation has no solution."
[Calculate grades’ average for a student] write a program that calculates the student grades’ average for a semester for the number of courses taken in that semester. Your program should do the following:
1.Read from user the number of courses (n)
2. Then, read the courses’ grades for n times (Hint: use a loop)
3.If a grade is grater than 100 or less than 0, ask the user to enter the grade again.
4.Calculate the average of grades using the following formula:
average = (sum of grades) / n
5.Print out the average grade on the screen.
Note: Always use appropriate data types.

- Q5: (Count positive and negative numbers and compute the average of numbers) Write a program that reads an unspecified number of integers, determines how many positive and negative values have been read, and computes the total and average of the input values (not counting zeros). Your program ends with the input 0. Display the average as a floating-point number. Here is a sample run: Enter an integer, the input ends if it is 0: 1 2 -1 3 0 The number of positives is 3 The number of negatives is 1 The total is 5.0 The average is 1.25arrow_forwardC# (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.arrow_forward(IN C LANGUAGE) Cumulative Addition: Computer selects a number between 7 and 23 at random. User will only add 2, 3 or 5 numbers to reach that number.For example: To reach 14: User will enter 5 5 2 2 (4 input).Also he can enter 2 2 2 2 2 2 2 (7 input) or 3 3 3 3 2 (5 input). https://www.bartleby.com/questions-and-answers/in-c-language-cumulative-addition-computer-selects-a-number-between-7-and-23-at-random.-user-will-on/0509c740-d993-44ed-a468-7e02da552600arrow_forward
- 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.

Sample Output: Enter the number of students: 6 Student I of 6 Enter student's score: 33.33 Student 2 of 6 Enter student's score: 89.56 Student 3 of 6 Enter student's score: 78.80 Student 4 of 6 Enter student's score: 93.3 Student 5 of 6 Enter student's score: 96.7 Student 6 of 6 Enter student's score: 85. 5.
