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
Q4: (Find the two lowest scores) Write a program that prompts the user to enter the number of students and each student’s name and score, and finally displays the student with the lowest score and the student with the second-lowest score.
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
3.

- (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_forward6. (Geometry: area of a pentagon) The area of a pentagon can be computed using the following formula (s is the length of a side): Area 5x s² 4 X tan TT 5 Write a program that prompts the user to enter the side of a pentagon and displays the area. Here is a sample run: Enter the side: 5.5 Enter The area of the pentagon is 53.04444136781625arrow_forward[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.arrow_forward

- 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_forwardIn C++ (Find the number of days in a month) Write a program that prompts the user to enter the month and year and displays the number of days in the month.
