2. Write a program with a user interface which allows the user to enter 2
integers. It should then give him the option of adding them, subtracting them,
multiplying them or dividing them. It should then print the result.

tell him whether the number is even or odd Use the truncating property of int
JAVA
Write a program that prompts the user to enter a line of text and displays the letter that has the most occurrences with the number of occurrences.
For example, if “I ate an apple.” was entered, the letter ‘a’ occurred the most often.
If not one but several letters have the most occurrences, all of them should be reported.
For example, since ‘o’ and ‘t’ appear three times in “I went to the zoo.”, both occurrences should be reported.
Sample Run:
Enter a line of text: I ate an apple.
The following letter(s) occurred most [3 time(s)]: a
Enter a line of text: I went to the zoo.
The following letter(s) occurred most [3 time(s)]: o t
Write the program allowing the user to input a string.
If the user inputs a capitalized letter within the string, such as ‘A’, have the program change all capitalized letters to lowercase.
This program should display the letter that has the most occurrences with the number of occurrences.

- Java question Write a program that plays the Rock-Paper-Scissors game againstthe computer. When played between two people, each personpicks one of three options (usually shown by a hand gesture) atthe same time, and a winner is determined. In the game, Rockbeats Scissors, Scissors beats Paper, and Paper beats Rock. The program should randomly choose one of the three options (with-out revealing it), then prompt for the user's selection. At that point, the program reveals both choices and prints a statementindicating if the user won, the computer won, or if it was a tie.Continue playing until the user chooses to stop, then print thenumber of user wins, losses, and ties.arrow_forwardPlease write a program which prints out the following story.

One morning Mary woke up to an awful racket: a dragon was approaching the village. Only Mary could save the village's residents. The story should change according to the input given by the user.

- Computer Science You must write code to test whether the reading from a sensor is within nominal values. Suppose the value from the sensor is stored in a variable with type double with the name sensor1. The nominal value for the reading is between 2.00 and 8.00, including 2 and 8. Write an if statement that outputs the message "OK" if the value of sensor1 is within the nominal range, and the message "Warning!" otherwise. You may assume that no precision errors will occur. Write only the if statement, no other statements like declaring function main, include directives, etc, are needed. in c++ please, urgent.arrow_forwardIn this assignment you will use the MyString class that you wrote earlier in this course. A palindrome is a string that reads the same forward and backward. Write a program that reads in any number of MyStrings from the user and determines if each MyString is a palindrome. The user will terminate each MyString by pressing the return (or enter) button. The user will indicate that there are no more MyStrings by entering "quit". To do this you must write a recursive function named isAPalindrome that takes a single MyString argument and two arguments that are bounds on MyString indices. The function must examine the part of the argument between the two bounds (including the bounds) and return true if this part of the argument is a palindrome, false if it is not a palindrome. The function must be recursive and must not call any other functions except ispunct(), isspace(), and toupper() (described below).

- Write an application that reads an integer and determines and prints whether it’s odd or even. [Hint: Use the remainder operator. An even number is a multiple of 2. Any multiple of 2 leaves a remainder of 0 when divided by 2.]arrow_forwardOBJECT: To compute the net pay of an employee, given his/her pay rate, number of hours, and tax rate. INPUT: his/her name, pay rate, and number of hours. You will prompt the user with a friendly message to enter the employee’s name, pay rate and number of hours. Note that you must use the dash (-) to connect the first name to the last name so that the name can be read using the cin statement. For example, John-Doe OUTPUT: the employee’s gross pay, tax deduction, and net pay. For example: Name: John-Doe Your gross pay is: 900.00 Your tax deduction is: 90.00 Your net pay is: 810.00 METHOD: the gross pay is the pay rate times the number of hours. The tax deduction is computed as follows: If the gross pay is less than 1000.00, it is 10% of the total pay; otherwise, it is 15% of the gross pay. The net pay is the gross pay minus the tax deduction. TOPICS:…arrow_forwardThe interest paid on a savings account is compounded daily. This means that if you start with startbal dollars in the bank, at the end of the first day you’ll have a balance ofstartbal * (1 + rate/365)dollars, where rate is the annual interest rate (0.10 if the annual rate is 10 percent). At the end of the second day, you’ll havestartbal * (1 + rate/365) * (1 + rate/365)dollars, and at the end of n days you’ll havestartbal * (1 + rate/365)ndollars. Write a program that processes a set of data records, each of which contains values for rate, startbal, and n and computes the final account balance.arrow_forward
