Question

// “You are on a 5-hour sea voyage. The ship sails at a speed of 40km per hour. Write a program that will output how many kilometers the ship has traveled by each hour.”

#include <iostream>

using namespace std;

int main()
{
int distance = 0;
//your code goes here
for (int x; x<=200; x+=40){

cout << x + 40 << endl;
}

return 0;
}

Answer 1

Tahiti🍷 , please edit your question and add description on top of your question. It will be easy to understand your question.

Here, you have given distance = 40 km per hour. So, you will be outputting only distance (instead of x + 40)

Hope this helps! :) 👍

Answer 2

Just one correction in for loop & one correction in your output statement Tahiti🍷 )

for (int = x) & check cout inside for loop

Rest of your code is good to go)

And, it happens don't worry. Slowly, you are going to code all steps correctly. 🙂👍

[correction for your code] 👇

#include <iostream>

using namespace std;

int main()
{
int distance = 0;
//your code goes here

for (int x =40; x <=200; x +=40)
{
cout <<""<< x << endl ;
}
return 0;
}

Shivani 📚✍ [Less Active] Thank you! I will try it. I don’t understand why I always answer every question correctly in the lesson, but then I get to the quiz and code incorrectly. 🤷🏽‍♀️

Answer 4

For anyone trying to figure this problem out do not follow the steps above. Below is the correct way to complete the problem.

#include <iostream>

using namespace std;

int main()
{

for (int x = 40; x<=200; x+=40){

cout << x << endl;
}

return 0;
}

“You are on a 5-hour sea voyage. The ship sails at a speed of 40km per hour. Write a program that will output how many kilometers the ship has traveled by each hour.”

Answer 6

#include <iostream>

using namespace std;

int main()
{
int distance = 0;
//your code goes here
for (int x; x<=200; x+=40){

cout << x << endl;
}

return 0;
}

// Your output:
0
40
80
120
160
200

Expected output:
40
80
120
160
200

Shivani 📚✍ [Less Active] What an awesome teacher (and scholar) you are! I know that you are going to ace your upcoming exams! Best wishes to you.

Answer 8

Why did you replace "distance" with "x" in for loop?
I'm doing this and it's not working

#include <iostream>

using namespace std;

int main()
{
int distance = 0;
//your code goes here
for (distance <= 0; distance + 40;){
cout << distance << endl;
}
return 0;
}

I suppose I could have used “distance” instead of “x” as the integer. The way I understand it, “0” is the starting distance, and must be increased by 40, up to 200. So distance can’t be <= 0. That would mean it has to be less than or equal to zero.

Answer 10

Tahiti🍷, I tried this and for some reason I ended up in an endless loop. I really don't understand it till now :/

Answer 11

Rami Moazzen
I myself am still learning C++, but I do know that you must instruct your program to stop the loop at some number, or it will loop endlessly. In this exercise, the sea voyage lasts 5 hours. So the distance loop must stop at the 5th hour. 40k per hour is 200k after 5 hours. Hence, for int=x, x<= 200. (The distance is less than or equal to 200k.)
