An array is a data structure that can hold multiple values of the same data type. When passing an array to a module, the entire array is copied and sent to the module as one unit.
Firstly, the module must have a defined parameter to receive the array. A parameter is a variable that is declared in the module and is used to receive the passed array. This parameter must be of the same data type as the passed array.
Next, an argument is used to pass the array to the module. An argument is the actual value of the array that is being passed. This argument is passed when the module is called in the main program.
Here is an example of pseudocode that demonstrates passing an array to a module:
// Declare a module that accepts an array as a parameter
Module calculateAverage(myArray[])
// Define a variable to store the sum
sum = 0
// Loop through the array and add each value to the sum
for i = 0 to length(myArray) - 1
sum = sum + myArray[i]
// Calculate the average
average = sum / length(myArray)
// Output the result
output "The average is " + average
End Module
// Declare an array in the main program
myNums[5] = {10, 20, 30, 40, 50}
// Call the module and pass the array as an argument
calculateAverage(myNums)
In the above example, the module "calculateAverage" accepts an array parameter called "myArray". When the module is called with the line "calculateAverage(myNums)", the array "myNums" is passed as an argument.
The module then loops through the array, adds up all values, calculates the average, and outputs the result.
This demonstration shows how an array is passed to a module using both parameters and arguments, and how it can be manipulated within the module to perform operations and return values to the main program.
Explain how an array is passed to a module. Your explanation must include an example with
pseudocode demonstrating the process. Include in your discussion explanations of parameters
and arguments.
Marks will be awarded as follows:
• Three marks explaining how an array is passed to a module.
• Three marks for a clear explanation of a parameter.
• Three marks for a clear explanation of an argument.
• Six marks for the pseudocode demonstrating the passing of an array to a module
