Conversions

The repository contains a boilerplate code for programs that do some sort of a unit conversion or mathematical calculations.

For each program there are tests being executed on the push and pull request to the repository. The tests for a correct program must pass.

1. Use only float64 variables in all programs.

2. Use the following functions:

   • fmt.Println
   • fmt.Scan

Submission

The workflow to complete and submit the assignment is the following:

1. In the top-right corner of the page, click Fork

1. The repository will be "copied" to your GitHub account.

2. Complete the assignment by commiting your changes to your GitHub repository. Make sure that the tests in Actions tab of the repository pass successfully.

3. Once done, create a Pull request to the original prog-1/unit-conversions repository.

   • Select Pull requests tab in your repository.
   • Click New pull request.
   • Click Create pull request.

Programs

Rectangle (2 points)

Directory rectangle.

The program must print the perimeter and the square of a rectangle given the rectangle (non-opposite) sides.

Example:

The program prints the perimeter and the square of a rectangle given the rectangle sides.
Enter the length and the breadth of the rectangle:
4 5.5
Perimeter: 19
Square: 22

Circle (2 points)

Directory circle.

The programm must print the perimeter and the square of a circle given the circle radius.

Example:

The program prints the perimeter and the square of a circle given the radius.
Enter the radius:
8
Perimeter: 50.26548245743669
Square: 201.06192982974676

You will need to use math.Pi constant to represent π value.

Speed (2 points)

Directory speed.

The program must convert the speed in km/h to the speed in m/s.

Example:

The program converts km/h to m/s.
Enter the speed in km/h:
100
The speed in m/s: 27.77777777777778

Temperature (2 points)

Directory temperature.

The program must convert Celsius degrees to Fahrenheit degrees. Finding a conversion formula is part of the exercise.

Example:

The program converts temperature from Celsius to Fahrenheit.
Enter the temperature in Celsius:
100
The temperature in Fahrenheit: 212

Quadratic equation (4 points)

Directory quadratic.

Given coefficients A, B, and C of a quadratic equation Ax^2 + Bx + C = 0, write a program that prints the equation solutions x1 and x2.

You will need to use math.Sqrt function to calculate a square root.

Example:

The program finds solutions of a quadratic equation.
Enter the coefficients A, B and C:
1 3 -10
x1 = 2
x2 = -5

Max and min (8 points)

Directory maxmin.

Write 4 programs (each in a separate subdirectory):

1. (maxmin/max2) a program that calculates the maximum of two numbers. You can use the following formula: max(a, b) = (a + b + |a - b|)/2. You will need to use math.Abs function to calculate an absolute value. Example:

   The program finds the maximum of two numbers max(a, b).
   Enter two numbers:
   5 7
   max: 7
   

2. (maxmin/min2) a program that calculates the minimum of two numbers min(a, b),

3. (maxmin/max3) a program that calculates the maximum of three numbers max(a, b, c),

4. (maxmin/min3) a program that calculates the minimum of three numbers min(a, b, c),

Resistance (3 points)

Directory resistance.

Write a program that calculates the resistance R of two resistors with the resistance R1 and R2 assuming that

1. the resistors R1 and R2 are connected in series, i.e. R = R1 + R2;
2. the resistors are connected in parallel, i.e. 1 / R = 1 / R1 + 1 / R2.

Example:

The program calculates the resistance R of two resistors.
Enter the resistance of two resistors:
4 8
Resistance when connected in series is 12; resistance when connected in parallel is 2.6666666666666665.
