Pseudo Code for Package Weight Management

Overview

This pseudo code outlines a program designed to input and store the names and weights of 50 packages. It validates the weights to ensure they fall within a specified range and subsequently identifies the package(s) with the least weight.

Pseudo Code Structure

1. Initialize Arrays

   • Create an array for storing names of packages.
   • Create an array for storing weights of packages.

2. Input Loop

   • Loop 50 times to gather inputs for each package.
     • Prompt user for package name.
     • Prompt user for package weight.
     • Validate weight:
       • If weight is between 30 and 250 kg (inclusive), store the name and weight.
       • If weight is invalid, display an error message and ask for input again.

3. Find Minimum Weight

   • Set a variable to hold the minimum weight, initialized to a large number (e.g., infinity).
   • Create an empty list to hold package names with the minimum weight.
   • Loop through the weights:
     • If the current weight is less than the minimum weight, update minimum weight and clear the list of names.
     • If the current weight is equal to the minimum weight, append the corresponding package name to the list.

4. Display Results

   • Print the name(s) of the package(s) that have the least weight.

Pseudo Code

BEGIN

    // Step 1: Initialize Arrays
    DECLARE packageNames[50]
    DECLARE packageWeights[50]

    // Step 2: Input Loop
    FOR i FROM 0 TO 49 DO
        PROMPT "Enter package name:"
        READ packageNames[i]

        VALID_INPUT = FALSE
        WHILE NOT VALID_INPUT DO
            PROMPT "Enter package weight (30-250 kg):"
            READ packageWeights[i]

            // Validate weight
            IF packageWeights[i] >= 30 AND packageWeights[i] <= 250 THEN
                VALID_INPUT = TRUE
            ELSE
                PRINT "Invalid weight. Please enter a weight between 30 and 250 kg."
            END IF
        END WHILE
    END FOR

    // Step 3: Find Minimum Weight
    DECLARE minWeight = INFINITY
    DECLARE minWeightPackages = []

    FOR i FROM 0 TO 49 DO
        IF packageWeights[i] < minWeight THEN
            minWeight = packageWeights[i]
            CLEAR minWeightPackages
            APPEND packageNames[i] TO minWeightPackages
        ELSE IF packageWeights[i] == minWeight THEN
            APPEND packageNames[i] TO minWeightPackages
        END IF
    END FOR

    // Step 4: Display Results
    PRINT "Package(s) with the least weight:"
    FOR EACH packageName IN minWeightPackages DO
        PRINT packageName
    END FOR

END

Summary

The pseudo code above demonstrates a clear and structured way to input, validate, and process package information. It emphasizes user interaction for data collection and ensures weight constraints are respected, ultimately identifying and displaying the package(s) with the least weight. This structure facilitates easy translation into any programming language and supports documentation and team communication.
