Question

Plss help. Construct a program in C++ to calculate the value when you perform the following operations using functions and keyboard input.
Addition
Subtraction
Multiplication
Integer division
Real division

Answer 1

So, your main function should probably present a menu and ask for input on which of the operations to perform (1-5 for Addition through Real division). From there, based on the input you can call functions that actually perform the operations. So, write an Addition() function, that then asks for input of two float values to add, then adds them, and prints the result. If the menu input in main, was "1", call the Add function.
Similarly, write functions for the other operations, and call them based on the input from the menu.

Hope that helped - trying to give you an idea without giving it all away ;)
