CPPForSchool.com: Flow of Control Set 2: Assignment 8

8. Write a program to calculate HCF of Two given number. 
Before I began coding, I had to confirm the meaning of HCF.  According to my research, HCF stands for Highest Common Factor or another well-known synonym would be GCD or Greatest Common Denominator.  Ultimately, I need to create a program that accepts two integers and then calculates the Greatest Common Denominator for both values.

For example, if the numbers inputted were 6 and 12, the HCF/GCD would be 6 because 6 can divide into itself and 12.

Below is my source and test outputs.  Of course, I have also included the sample source and output for comparison.

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...

6. P is one-dimensional array of integers. Write a C++ function to efficiently search for a data VAL from P. If VAL is present in the array then the function should return value 1 and 0 otherwise. For this assignment, I was not able to decipher what VAL was supposed to represent.  Presumably, it stood for value, but I was not 100% sure so I went ahead and reviewed the sample code.  With that said, I coded this assignment using functions once again.  Also, using bool was quite interesting.  I was unaware of how flexible bool can be utilized.  I have learned a great deal with this assignment.  Nevertheless, below is my source code along with the sample 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.
