Show the result of expression or error if incorrect.Evaluating Postfix ExpressionEvaluating Postfix ExpressionEvaluating Postfix ExpressionInput an expression:2 10 + 9 6 - /Input an expression:2.0 10 + 9 6 - /Input an expression:2 10 + 9 - /Result = 4.0Result = 4.0Result = Error(Sample run of the program )Note :• Input expression will be a String. After the input, parse the string for numbers and operators.Operands may be integers, and floats or doubles. Hence use a stack which can store doubles.• A simple example is available at [ https://courses.cs.washington.edu/courses/cse143/12su/lectures/06-27/programs/Postfix.java ]. Modify it for input of expression from user and use of doubledata type so that it should work for both integers and doubles.• Postfix expression consists of numbers(integers/doubles), +-*/, and spaces such as "2 3.0 - 4 *"

Write a c++ program that makes a calculator that gets two integer hexadecimal numbers from user and shows their sum in hexadecimal. The output should be shown as addition sums are done on paper, e.g. a sample output is shown below: Enter 1st number in hex: FF16 Enter 2nd number in hex: ABC FF16 + ABC ------------ 109D2 Note: The hex and oct manipulators work with input streams for integer data types as well. Try this code to verify it. int x; cin >> hex >> x; //provide FF as input cout << x; //the decimal equivalent of hex value FF shown

This is for C++: Design a program that simulates a lottery game. The California SuperLotto game is a perfect example of a lottery game. The SuperLotto game is designed to print five number randomly between 1 and 47 in one straight line, plus one random mega number between 1 - 27. Design a program that mimics this popular California game. Ask the user for the number of lines to play (keep it at no more than 5 lines) The output prints the number of lines Next, print the mega number(s). Remember, the mega must equal the number of lines requested. For example, one line of SuperLotto would equal one mega number. Same would be for five lines of SuperLotto (5 SuperLotto = 5 mega numbers). The numbers do not need to be in neither ascending nor descending order. Validate your input by not allowing the user to enter a 0 for the number of lines to play. Display a message that says, "Incorrect value. Must be greater than 1". You output should look like the attached picture:

NEED A C++ PROGRAM CODE IN VISUAL STUDIO AND OUTPUT. Write a program in C++ that lets the user enter some English text, then converts the text to Pig-Latin. For your understanding Pig-Latin takes the first letter of a word, puts it at the end, and appends “ay”. The only exception is if the first letter is a vowel, in which case we keep it as it is and append “hay” to the end. For example: “hello” à “ellohay”, and “image” à “imagehay”. Please note that your program should able to process the sentence as well.
