Using User Input to Assign Variables
Problem Statement:

The first driveDistance() will drive the linkbot forward 5 units. The program will then prompt you to input the rest of the distance, so the linkbot will reach the green dot.

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

robot.driveDistance(5, radius);
robot.delaySeconds(0.3);
distance = 10;
robot.driveDistance(distance, radius);
