Program Plan Intro

Random walk

Program Plan:

Import the header file.

Define the main method.

Call the “printIntro ()” method.

Get the input from the user.

Call the “avgSteps ()” method and store it in a variable.

Display the result.

Define the “printIntro ()” method.

Display the messages.

Define the “avgSteps ()” method.

Set the value

Iterate “i” till it reaches 1000

Call the “simNSteps ()” method

Calculate the “totTravel”

Check “totTravel” is equal to 0

Set the value

Otherwise, calculate the “avgTravel”

Return the result.

Define “simNSteps ()” method

Set the value

Iterate “i” till it reaches “n”

Calculate “x” value

Check “x” is greater than 0

Increment the “steps” value

Check “x” is less than 0

Decrement the “steps” value

Otherwise, set the value

Return the result.

Call the main method.
