7.  What is the output of following program?

 Once again, I am being tested on my comprehension of order of operations and mathematics within C++.  Below is a screen shot each question.


Order of left to right.

int x = 10, y;
y = x++;
cout << y;

Answer: 10  

int x = 10, y;
y = x++;
cout << x;

Answer: 11


 int x = 10;
x++;
cout << x;

Answer: 11

 int x = 10, y;
y = ++x;
cout << y;

Answer: 11

 int x = 10;
cout << ++x;

Answer: 11

 int x = 10;
cout << x++;

Answer: 10
For the sake of continuity, I have included the "Show the answer" screenshot, followed by the source and output for each problem.

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...
