Conditional Statement If: Making Decision Based on a Specified Condition

The if statement executes a sequence of codes only when a certain condition is met/true.

The condition to be tested is a logical stament, i.e "Does this number = 3". If yes, the block returns a 1 and if block executes the inside statement. If no, the block returns a 0, and the if- block is skipped. 

The if- statement and all the logic blocks are under the Logic tab or Math tab. 

Watch the video to learn more about how to use the if- statement.

If Statements Using Random Integers to Drive the Robot a Specified Distance
Problem Statement:

Insert a condition so that the robot only drives when the random number between 1 and 100 is even.

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

variable = randint(1, 100);
printf("variable is %g \n", variable);
if (variable % 2 == 0) {
  robot.driveDistance(5, radius);
