- Retail StoreSuppose you have been consulted by a retail shop around your area to build a simple calculator. The calculator must be able to perform arithmetic operations (+, -, *, /) on integers. The program receives an expression from the user. The expression is structured as follows: integer input followed by an operator and another integer input from user prior to displaying the final result. Write a Java application that can perform the above expression. Create a method that takes two parameters and performs an arithmetic operation on the passed values. Your final output should consist of the expression and the result.Can a method be written to return any type of data?Code in C# (OOP Concept) Do a program that does the following: Ask for a number from the user in the main method o Pass thenumber to a method call it "Multiplication”. In the Method Multiplication, multiply the number by a number enteredby the user (mention that the number should be positive). Send the result back to the main and print it from the mainModify the previous program if the user enters a negative second number in the method Multiplication, do not acceptthe number and ask the user to reenter it again. . Add another method call it also Multiplication Ask for a float numberfrom the main and send it to the new Multiplication. This method should also ask for another positive number fromthe user and multiply it by the float number. Design and implement a function called "multiply" in C++ that accepttwo numbers and returns either the arithmetic multiplication or repetition of a given string a specific number of timesdepending on the data types of the argument values.
