C++ Create a program that reads a simple arithmetic expression and evaluates it. More precisely, the program reads from the user a line of text that’s supposed to contain two numbers separated by an arithmetic operator, as in: 35.6 + 12 The program then prints back the expression and its value, as in: 35.6 + 12 = 47.6 The program should verify that the input line contains two numbers, one operator and nothing else. There can be whitespace before the first number, after the second number and between each number and the operator. The operator can be either +, −, *, or /. In case of an error, the program should print: "Invalid expression" and quit. When the program prints the expression, there should be no whitespace before the first number and there should be exactly one blank space before and after the operator and the equal sign. Use string streams.

Qn1: You are asked to write a simple C program that will accept an integer value in the range of 5-95 and as a multiple of 5 representing the number of cents to give to a customer in their change. The program should calculate how many coins of each denomination and display this to the user. Valid coin values are 50, 20, 10 and 5. Your solution (program and algorithm) should be modular in nature. This requires the submission of a high-level algorithm and suitable decompositions of each step. Note that for this problem the principle of code reuse is particularly important and a significant number of marks are allocated to this. You should attempt to design your solution such that it consists of a relatively small number of functions that are as general in design as possible and you should have one function in particular that can be reused (called repeatedly) in order to solve the majority of the problem. If you find that you have developed a large number of functions which each performs...
