Question

To see how the four steps of the software development procedure discussed in Section 1.7 can be applied in practice, you apply them to the following simple programming problem:

The circumference, C, of a circle is given by the formula C = 2ðr,
where ð is the constant 3.1416 (accurate to four decimal places)
and r is the radius of the circle.
Using this information, write a C++ program to calculate the circumference
of a circle that has a 2-inch radius.

Answer 1

Read the four steps of the software development procedure in Section 1.7. If you understand it, you should be able to answer the problem

Answer 2

To solve this programming problem, we can follow the four steps of the software development procedure.

Step 1: Problem Analysis
In this step, we need to analyze the problem and understand what needs to be done. We are given the formula for calculating the circumference of a circle, which involves the constant π (pi) and the radius of the circle.

Step 2: Algorithm Design
In this step, we need to design the algorithm that will solve the problem. The algorithm will involve using the given formula and plugging in the values to calculate the circumference.

Step 3: Implementation
In this step, we will implement the algorithm in the C++ programming language. We need to write the code that will calculate the circumference of a circle with a radius of 2 inches.

Here's the C++ code that calculates the circumference:

```cpp
#include <iostream>
using namespace std;

int main() {
const double pi = 3.1416;
double radius = 2.0;
double circumference = 2 * pi * radius;

cout << "The circumference of a circle with a radius of 2 inches is: " << circumference << " inches" << endl;

return 0;
}
```

Step 4: Testing and Debugging
In this step, we need to test the program to ensure it is working correctly and make any necessary adjustments. You can compile and run the code to see the output. It should display the circumference of the circle with a radius of 2 inches.

So, to solve this specific programming problem, you would need to follow these steps – analyze the problem, design the algorithm, implement the code in C++, and test it to make sure it works correctly.
