CPPForSchool.com: Variable, Operator & Expression Set 1: Assignment 10

10. Write a program to check whether the given number is even or odd (using ? : ternary operator)

Ternary operator is alive and well with this exercise.  Unlike the previous assignment, I felt that this is a much better use case for a ternary operator.  I say this because numbers can only be either one of two types, odd or even.  Luckily, zero is classified as an even number so I no longer have any gripes with the assignment.

Nevertheless, for this assignment I had to use the modulo or modulus operator.  Essentially, it is the process of division and presenting the remainder.  For example, 5/2 would equate to 2 with a remainder of 1.  The quickest way to accomplish this would be 5 mod 2 or in the case of C++ 5%2.  With that said, below is the source code for this assignment.



Below is the output.  The program is able to successfully determine if the number is either odd or even.



Admittedly, I am becoming more confident with coding.  It is only day 2 and I have completed all 10 assignments.  This concludes Variable, Operator & Expression Assignment Set 1.  Onward to Assignment Set 2.

9. Write a program to check whether the given number is positive or negative (using ? : ternary operator ) This assignment had my computer science senses tingling, in a very bad way.  For this particular assignment, I had to code a program that utilizes a ternary operator for determining if a number is positive or negative.  In concept this should be rather simple, but reading it hasn't been too easy.  From what I understood, ternary operators function much like a shorthand if/else statement.  Nevertheless, below is the source code and output. Although there everything outputted as expected, there is a minor issue.  If the user decides to input a zero, regardless of the instruction, it will output incorrect information. Example 1: "23 is a positive number."  <--Correct! Example 2: "-123 is a negative number."  <--Correct! Example 3: "0 is a negative number." <--Wrong! Once again, I would like to point ...

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.

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...
