CPPForSchool.com: User Defined Function Set 1: Assignment 9

9. Give the output of the following program.

 
#include <iostream>
using namespace std;

int global = 10;

void func(int &x, int y)
{
    x = x - y;
    y = x * 10;
    cout << x << ", " << y << '\n';
}

int main()
{
    int global = 7;
    func (::global, global);
    cout << global << ", " << ::global << '\n';
    
    func(global, ::global);
    cout << global << ", " << ::global << '\n';
    
    return 0;
}

8.        Write a program to calculate area of circle.   Once again, math has reared its focus on an assignment.  Luckily, with the power of search engines, I was able to rediscover the equations for calculating the area of a circle.  However, there are some requirements.  In order to calculate the area of a circle, the user will need to provide one of the following: radius, diameter, or circumference.   Also, here is a quick rundown of the variables.   A = Area  π = pi  r = radius  D = diameter  C = circumference   According to MathIsFun , the area of a circle can be calculated using one of the following formulas.  **Fun fact, in order to type the pi symbol "π", hold down ALT + 2, 2, 7. -- WikiHow **  **For the exponent of 2, hold down ALT + 2, 5, 3. -- AZCentral **    A = π r²                     π  (Pi) times the Radius squared        A = ( π / 4 ) * D²      when you know the Diameter A = C² / 4...

2.        Write a C++ program to swap first and last element of an integer 1-d array.     This assignment was not too difficult, but it did take some time for me to figure how to reference the last element value.  Luckily, I was able to simply use "x-1" in order to reference the last value.  Nevertheless, I have continued to use my base template in regards to coding style.  Everything has been broken into functions.  Also, I used a lot of the same code from the prior assignment in order to create this assignment.            It is important to note that I commented out the initial test code to ensure I understood how to execute this task at a very base minimal level.  Learning from the prior assignment, I reused the temp1/temp2 variables in order to store the values accordingly.         Here is the sample source code for comparison.

7.        Write a program to swap the values of two    variables.   This program was not too difficult.  Swapping values between two variables will require a third variable, specifically to act as a placeholder for temporary storage.  Basically, once the user inputs a value for the first variable, it is immediately placed into temporary storage.  Once the user inputs the second value, it is copied over to the first variable followed by copying the placeholder value into the second variable.       To keep things simple, I tested the code by inputting 1 as x value and 2 for the y value.
