Design a function named findMax that accepts two integer values as arguments and returns the value that is the greater of the two. For example, if 7 and 12 are passed as arguments to the function, the function should return 12. Use the function in a program that prompts the user to enter two integer values. The program should display the value that is the greater of the two. The following modules should be written:

getNum, that accepts a Ref to an integer, prompts the user to enter an integer, and accepts that input

findMax, that accepts two integer values and returns the value that is the greater of the two

showMaximum, that accepts two integer values, calls findMax, and displays the number returned from findMax

The main module, that will call getNum twice to enter two numbers, and showMaximum.

My main question is how do pass information from a module to function in pseudocode.
