C++

Write a program called RoomDiag.cpp that calculates the longest diagonal of a room with user-specified dimensions. The program MUST contain the following features: A void function askDims (...) that asks the user for the width, length, and height of a room. A void function calcDiag (...) that calculates the longest diagonal for a room with an input width, length, and height. User input may only be taken in askDims (...). Input validation no negative dimensions! Hint: Use reference variables as your width, length, and height parameters (6.13 in your book). Also, the longest diagonal of a room is illustrated below. Where , 1 = length vw = width h = height d = diagonal
