Pseudo Code for Finding the Lowest Value in a 1D Array of Temperatures

Overview

This pseudo code aims to find the lowest value in a one-dimensional array called Temperatures[], which contains 25 elements. The values of the array will range between -20 and 100 inclusive.

Pseudo Code

BEGIN
    // Initialize the variable to hold the lowest temperature
    SET LowestTemperature TO a very large value (e.g., 101)

    // Loop through the array elements from index 1 to 25
    FOR index FROM 1 TO 25 DO
        // Check if the current temperature is less than the current lowest temperature
        IF Temperatures[index] < LowestTemperature THEN
            // Update the lowest temperature
            SET LowestTemperature TO Temperatures[index]
        ENDIF
    ENDFOR

    // Output the lowest temperature found
    OUTPUT "The lowest temperature is: ", LowestTemperature
END

Key Points

1. Initialization:

   • Start with LowestTemperature set to a value higher than the maximum expected temperature to ensure that any value in the array replaces it.

2. Single Loop:

   • A single loop iterates through each element of the Temperatures[] array from index 1 to 25.

3. Condition Check:

   • Inside the loop, an IF statement checks whether the current temperature is less than LowestTemperature. If true, it updates LowestTemperature.

4. Output:

   • Once the loop completes, the lowest temperature found is printed.

This structure is efficient and conforms to the requirements specified for working with a one-dimensional array and finding the minimum value using a single loop.
