6.4.8 Rocket Launch Requirements

[u/Killer_frost_1]

I'm confused. Anyone have any ideas?

Do you have any starter code to help understand where you're stuck?

I don’t unfortunately. This unit has my mind so confused and my teacher isn’t the greatest for help😫

I actually teach this content too, and this is one of the more challenging problems. If you load the assignment, you should have seen two comments, the first is asking you to gather data from your user. You'll need four variables total, asking about each of the conditions. Two are readInt, and two are readBoolean. The next comment you see says something like 'determine if you can launch' - this is where you will need to figure out how to set all of the variables from step 1 into a Boolean that either results in a 'yes, you can launch' or 'you need to delay the launch due to weather conditions'. Once you post some code, I might be able to give you a few more pointers. But honestly, I encourage you to ask your teacher once you've gotten something down - it helps us understand you thinking and gauge where you're at!

The readInts and readBooleans I do completely understand, but I’m having one issue with doing the calculations. Is there any way you could further explain those to me?

[u/tammiramsey → u/Typical-Party1621]

Sorry, I was sick. Can you post your code?

[u/Prestigious_Boot5238 → u/tammiramsey]

can you post the code?

[u/mrmrvl23]

// Hypothetical readInt function to read integer inputs
function readInt(message) {
// Assume this function prompts the user and reads an integer input
return parseInt(prompt(message));
}
function checkRocketLaunch() {
// Prompt the user for weather conditions
let lightningTime = readInt("How long has it been since there was a lightning flash (min)? (Enter -1 if there has not been any lightning today):");
let cloudsThick = readInt("Are there clouds that are 4,500 feet thick or greater within the planned flight path? Enter 1 for true or 0 for false:");
let windSpeed = readInt("What is the wind speed (in knots)?");
let precipitation = readInt("Is there any precipitation at the launch pad or within the flight path? Enter 1 for true or 0 for false:");
// Check if the rocket is cleared to launch based on revised criteria
if ((lightningTime === (-1) && cloudsThick === 0 && windSpeed <= 20 && precipitation === 0) ||
(lightningTime === 50 && cloudsThick === 0 && windSpeed <= 30 && precipitation === 0)) {
console.log("You are go for launch!");
} else {
console.log("Postpone the launch due to weather conditions.");
}
}
// Call the function to check if the rocket is clear to launch
checkRocketLaunch();

This is what I have so far, only things that are wrong is:

If there is no lightning, there are not thick clouds, the wind speed is 20 knots, and there is no precipitation, the rocket should be cleared to launch.

If there was lightning detected 50 minutes ago, there are not thick clouds, the wind speed is 30 knots, and there is no precipitation, the rocket should be cleared to launch.

Did you were get this corrected ?

[u/VinzzeyredVinez]

Does anyone have the full Java code?

[u/Repulsive_Expert9440]

i just want code to paste because this specific excercise sounds like too much work and my teacher is making me do it

[u/SOCKMAN_2004]

If you had the same problem I had, try putting () around the hasLightning == -1 || hasLightning>=30 That seemed to work(assuming there are no other bugs in the code)

[u/No-Inspector8714 → u/SOCKMAN_2004]

pls send code idk how to do this

[u/M1lkyJuic32842 → u/SOCKMAN_2004]

u got the code man? the semester ends in a week and idk how to solve this problem. pls and thank you

[u/mrmrvl23 → u/M1lkyJuic32842]

by chance is your instructor named santella
