(2) Write a Jeva progrom thet prompts the user to enter two integer numbers a and b,then it computes the value of a reised to the power of b. The integer number shouldbe typed in by the user in response to a prompt message. Aleays check the number bis a positive number, so your progrom must keep asking the user to enter b until theuser enters a positive number. So, your program must keep asking the user to enter b,until the user enters a positive rumber.Hint:If a= 2 and b = 3, then:2'-2 2- 0:Your program must consider the following specifications• Use Power as the name of your class.• De NOT use Math powla, b)• Type your name ond student number obove the class declaration using ablock/parogroph comment.• Use documentation, comments ond code style• Use significant and appropriete identifiers.• Use appropriate data type for the variables.• Use long type to hold the result.Here are sample runs of the progromEnter a nunber: 2Enter b number: 3The value of 2 raised to the power of 3 is 8

(2) Write a Jeva progrom thet prompts the user to enter two integer numbers a ond b. then it computes the value of e raised to the power of b. The integer number should be typed in by the user in response to a prompt message. Always check the rumber b is a positive number, so your program must keep asking the user to enter b until the user enters a positive number. Se, your program must keep asking the user to enter b. until the user enters a positive number.

17.Write a Java program that prompts the user to input an integer greater than 0 which represents the size/height of the triangle shape. The program should print the following triangle shape according to the user input by alternating 'f' and '+' characters. Invalid error message must be displayed if the size is less than 1. Example: if the size of the shape = 4, then the p program should output: ! !+! !+!+! 1+1+1+1
2. Develop a program which prompts the user to input a whole number greater than 2. All invalid input must be rejected, including whole numbers 2 or less. The program then outputs all prime numbers starting at 2, which are less than the number input by the user.
23. Write a program to read a 4-digit number. Display the sum of all the digits. Eg: Number = 2341 Sum of the digits is: 10 24. Your advisor has asked you to write a program which will help him/her to find number of courses to be allotted to his/her advisee. CGPA >=2.75 6 courses can be taken CGPA=2.0 5 courses can be taken CGPA<2.0 4 courses can be taken Advisor should be able to input name of advisee and CGPA. Program should give the output as follows "Amir can take 6 courses in the semester".
Exercise 3: Write a Python program that reads from the user an integer n between 1 and 20, and then computes and prints all intermediary summations from 1 up to and including n. Where the ith intermediary sum is given by "1+2+...+i". Note that your program should display a suitable error message if n is located outside the range specified (1
Write a program that prompts the user to input an integer between 0 and 35. If the number is less than or equal to 9, the program should output the number; otherwise, it should output A for 10, B for 11, C for 12 . . . and Z for 35. (Hint: Use the cast operator, static_cast(), for numbers >= 10. E.g; static_cast('A'+1) will evaluated to B)
Write the missing statements in the following program so that it prompts the user to input two numbers. If one of the numbers is 0 or negative, the program outputs both numbers must be positive. If both the numbers are equal, it outputs the sum of the numbers; if the first number is less than or equal to 2 and both the numbers are not equal, it outputs second number to the power of the first number; otherwise it outputs the product of the numbers. #include <iostream>//Include additional header files, if necessaryusing namespace std;int main(){double firstNum, secondNum;cout << "Enter two nonzero numbers: ";cin >> firstNum >> secondNum;cout << endl;//Missing statementsreturn 0;}

Write a program to request for three number, your program should determine: i. the largest of the number ii. the average of the numbers You NB: the numbers are of type int and Scanner must be used. b. The electoral commission of Ghana is trying to find out the eligibility of voters in the country, on a trial bases you were tasked to come out with a program that request for: i. A person's country of residence; ii. The person's age; iii. The person should be eligible to vote if he comes from Ghana and is at least 18 years of age. NB: country and age should be declared as string and float respectively, You can use either "Scanner of JOtionPane" to collect the variables bor 1 of 1 125 words DR English (United States).
the number of students in a course. The program should then read that many student Write a program that prompts the user to input an integer number, which represents marks as floating point numbers. Your program should then print the average score to the screen. PQ2 If the user inputs an invalid number of students, your program should print an appropriate message and terminate unsuccessfully.
How do you: Construct a program that calculates the course overall grade point average (GPA). The program must input 3 scores for each of the categories listed in the calculation of the GPA provided below with exception of the final examination. The maximum score for all quizzes is 20 points each, the maximum score for all homework assignments is 50 points each, the maximum score for all tests and all programming assignments is 100 points each, and the maximum for the final examination is 120 points. You can select the scores that you make on each of these assessed items. Assignments Scale Homework 10 % Programming Assignments 25 % Quizzes (Weekly) 15 % Tests 30 % Final Examination 20 % You must develop the formula for calculating the GPA using the information provided in the table. For example if the final examination has a maximum score of 120 and you get an 85. Then your weighted score for the final examination is calculated using the…
