-## Algorithm
-
-- step 1 Prompt User for Number of Courses:
-Display a prompt asking the user to enter the number of courses.
-Read the user input and store it in the variable numCourses.
-
-- step 2 Validate Number of Courses:
-
-Check if numCourses is less than or equal to 0.
-
-If true, display an error message and exit the program with an error code.
-
-- step 3 Initialize Variables:
-Initialize totalCredits and totalGradePoints to 0.0.
-
-- step 4  Loop for Each Course:
-Use a for loop to iterate from 1 to numCourses.
-
-- step 5 Inside the loop:
-
-Display a prompt for course details (course number).
-Read and store user input for course credits in the variable credits.
-Read and store user input for course grade in the variable grade.
-
-- step 6 Validate Grade:
-Check if grade is outside the valid range of 0 to 4 (on a 4.0 scale).
-If true, display an error message and exit the program with an error code.
-
-- step 7 Update Total Credits and Grade Points:
-Add credits to totalCredits.
-Add the product of credits and grade to totalGradePoints.
-
-- step 8  Calculate GPA:
-Calculate the GPA by dividing totalGradePoints by totalCredits. Store the result in the variable gpa.
-
-- step 9 Display GPA:
-Display the calculated GPA with two decimal places.

-Prompt the user to choose between Celsius to Fahrenheit (1) or Fahrenheit to Celsius (2).
+1. Start
+
+2. Input choice
+   a. Display "Choose conversion:"
+   b. Display "1. Celsius to Fahrenheit"
+   c. Display "2. Fahrenheit to Celsius"
+   d. Display "Enter choice (1 or 2): "
+   e. Read choice from the user
+
+3. Input temperature
+   a. Display "Enter temperature: "
+   b. Read temperature from the user
+
+4. Switch on choice
+   - Case 1:
+      a. Display "X Celsius is equal to Y Fahrenheit" where X is the entered temperature and Y is the result of celsiusToFahrenheit function with the entered temperature
+      b. Break
+   - Case 2:
+      a. Display "X Fahrenheit is equal to Y Celsius" where X is the entered temperature and Y is the result of fahrenheitToCelsius function with the entered temperature

-Read the user input for temperature and store it in the variable temperature.
-
-- Perform Temperature Conversion:
-Use a switch statement to check the user's choice and perform the corresponding temperature conversion.
-
-If the choice is 1, call the celsiusToFahrenheit function and display the result.
-
-If the choice is 2, call the fahrenheitToCelsius function and display the result.
