Else-If Statements: Using Random Integers to Drive the Robot to a Specified xy Coordinate
Problem Statement:
Modify the if-statement so that the robot travels to (0,5) if a random number between 1 and 100 is less than 30, to (5,5) if it is equal or greater than 70, otherwise, to (5,0).
```/* Code generated by RoboBlockly v2.0 */
#include <linkbot.h>
double variable;
CLinkbotI robot;
double radius = 1.75;
double trackwidth = 3.69;

variable = randint(1, 100);
printf("variable is %g \n", variable);
if (variable < 30) {
robot.driveDistance(5, radius);
}
else if (variable >= 70) {
robot.turnRight(45, radius, trackwidth);
robot.driveDistance(7.07, radius);
}
else {
robot.turnRight(90, radius, trackwidth);
robot.driveDistance(5, radius);
}
