Explanation of Solution

The program execution is explained in the in-lined comments:

#include <iostream> 

#include <iomanip>

using namespace std; 

int main()  

{  

    //declare pointer variables and allocate memory

    double *trip1Cost = new double;

    double *trip2Cost = new double;

    double *trip3Cost = new double;

    double *max;

    //store values in the allocated memory 

    *trip1Cost = 100.00;

    *trip2Cost = 350.00;

    //assign pointer variables to each other

    //trip3Cost now points to location having 

    //stored 350.00 later trip2Cost points

    //to location having a stored value 100.00

    trip3Cost = trip2Cost;

    trip2Cost = trip1Cost;

    //trip1Cost is now pointed to freshly allocated

    //memory location and assigned value

    trip1Cost = new double;

    //trip1Cost points to a location having

    //stored value of 175 and trip3Cost now

    //points to a location having a stored value 275

    *trip1Cost = 175;

    *trip3Cost = 275;

    //sets the output format

    cout << fixed << showpoint << setprecision(2);

    //prints the arithmetic expression

    //(*trip1Cost + *trip2Cost + *trip3Cost) which

    //evaluates to (175 + 100...

C++ Write a program that takes as input an arithmetic expression followed by a semicolon ;. The program outputs whether the expression contains matching grouping symbols. For example, the arithmetic expressions {25 + (3 – 6) * 8} and 7 + 8 * 2 contains matching grouping symbols. However, the expression 5 + {(13 + 7) / 8 - 2 * 9 does not contain matching grouping symbols. If the expression contains matching grouping symbols, the program output should contain the following text: Expression has matching grouping symbol If the expression does not contain matching grouping symbols, the program output should contain the following text: Expression does not have matching grouping symbols.
In c++
in Swift Programming: The Big Nerd Ranch Guide (2nd Ed.) e-book: Repeat the silver challenge, but this time make sure that the formatting above matches what you print to the console. You may need to search the documentation for how to represent special characters in String literals (e.g., how do you represent a newline in a String?). You will also want to look at the documentation for the print() function to use a new parameter called terminator. This parameter defaults to printing a new line after each String logged to the console, but you will want to do something else. There are many ways to solve this challenge, but one way would be to print a String with a certain number of empty spaces (it is up to you to figure out how many!) when you print specific zip codes.
