Greetings, future programmer! Today, we'll be diving into the world of loops and conditional statements in Dart. Imagine this — you're in charge of an AI system that controls a fleet of drones. Your primary responsibility is to ensure the drones have sufficient battery power for their missions. This interesting scenario will be replicated using Dart's loops and conditional statements.
Loops and conditionals in programming perform tasks until a certain condition is met. Let's say your job is to verify the battery status of each drone before it embarks on its mission. This is when we can take advantage of the power of combining Dart loops with conditional statements.
A for
loop is as reliable as our dedicated AI algorithm. It helps us perform checks and maneuvers in our code like a well-oiled machine. Now, using the for
loop and a conditional statement, we'll manage the drone's battery efficiency status before it begins its task!
Dart1// List of drones (true means the battery is efficient, false means not) 2var dronesBatteryStatus = [true, true, false, true, false]; 3 4// A 'for' loop to check each drone's battery status 5for (var i = 0; i < dronesBatteryStatus.length; i++) { 6 // An 'if-else' statement to validate the drone's battery status 7 if (dronesBatteryStatus[i]) { 8 print('Drone ${i + 1} : Battery is efficient.'); 9 } else { 10 print('Drone ${i + 1} : Battery is not efficient.'); 11 } 12} 13/* 14Prints: 15Drone 1 : Battery is efficient. 16Drone 2 : Battery is efficient. 17Drone 3 : Battery is not efficient. 18Drone 4 : Battery is efficient. 19Drone 5 : Battery is not efficient. 20*/
In this example, we used a for
loop to inspect the battery efficiency status of each drone.
Now, let's look at while
loops! In the same way a conscientious mission operator waits until all system checks have been completed for each drone, we'll combine this idea with a while
loop and conditional statement.
Dart1// List of drones (true means ready for mission, false means not ready) 2var dronesMissionStatus = [true, true, false, true, false]; 3 4// Here, 'i' denotes the number of drones inspected 5var i = 0; 6 7// A 'while' loop to check each drone's mission status 8while (i < dronesMissionStatus.length) { 9 // An 'if-else' condition within our loop 10 if (dronesMissionStatus[i]) { 11 print('Drone ${i + 1} : Ready for mission.'); 12 } else { 13 print('Drone ${i + 1} : Not ready for mission.'); 14 } 15 i++; // 'i' is incremented by 1 for each drone checked 16} 17/* 18Prints: 19Drone 1 : Ready for mission. 20Drone 2 : Ready for mission. 21Drone 3 : Not ready for mission. 22Drone 4: Ready for mission. 23Drone 5 : Not ready for mission. 24*/
In this case, our while
loop diligently checks the mission readiness status of each drone until all drones have been inspected.
Kudos on the successful mission! In today's session, we learned how to combine loops with conditional statements, enhancing your understanding of Dart control flow. You now have the knowledge to implement these concepts in your upcoming coding assignments. As we journey further into the world of programming, let's remember that practice makes perfect!
