Function: Creating a Generalized Program

In a program, you sometimes need to create multiple tasks and each task needs a list of codes. For example, "Get Ready for Bed" program includes "Brush Your Teeth", "Change Your Clothes", and "Go to Bed" tasks. Each task has differnt movement. 

A function performs a task. Functions allow you to code multiple tasks inside a big program. 

Watch the lesson video to learn more about functions.

Functions: Creating a Square
Problem Statement:

The createSquare function will draw a square. Use this function to draw two squares of length 4: Square 1 is centered at (3, 3) and Square 2 is at (9, 12). For a challenge, trace only the two squares.

/* Code generated by RoboBlockly v2.0 */
#include <linkbot.h>
CLinkbotI robot;
double radius = 1.75;
double trackwidth = 3.69;
int count;

// Describe this function...
void createSquare() {
  robot.traceOff();
  robot.driveDistance(2, radius);
  robot.turnRight(90, radius, trackwidth);
  robot.traceOn();
  count = 0;
  while(count < 4) {
    robot.driveDistance(2, radius);
    robot.turnRight(90, radius, trackwidth);
    robot.driveDistance(2, radius);
    count = count + 1;
  }
}

robot.traceOff();
robot.drivexyTo(3, 3, radius, trackwidth);
robot.traceOn();
createSquare();
robot.traceOff();
robot.drivexyTo(9, 12, radius, trackwidth);
