What is it you are trying to achieve?
im trying to finish my homework
What is the problem you are having?
i do not understand this question so i do not know how to code it
the question:
Write a program that prompts for an initial amount of money and an annual interest rate, then calculates how much money will be accumulated in 20 years.
Also for this i have to use the " For loop "
Describe what you have tried to solve this problem
i tried asking friend but they don't get it either =/
Post any relevant code (You may choose to attach the file instead of posting the code if it is too long)
I took a shot at it but failed.. so confused
Turing: |
var initial, annual,years: int
years := 20
put "What is the initial amount of money? "
get initial
put "what is the annual interest rate? "
get annual
for accumulated : initial..years by annual
put accumulated
end for
|
Please specify what version of Turing you are using
latest version i think |

Just so you know:
At this forum, we are here to HELP you not DO the work for you.
So if you have any specific questions, feel free to ask.
HINT: You do not have to use for. And if you want to keep years constant, you could declare it as:
Turing: |
const years: int := 20

i get what yours saying but can you explain how i could do this i don't understand the question so i don't know how to code it. my teacher also told me to use for loop or she won't mark it =/ |

What. Was. That?
An explanation for the question: when someone invests some money, that amount typically earns some profit, as a percent increase. That is known as interest. So if I started with $100 and the interest rate is 10% per year, then after a year I would have $110. If I waited another year, it would be $121. Etc. The question asks about the amount I would end up with in 20 years. |

in Turing, the variable type you are looking for is called real |

ohhh yea!! forgot about that didn't use it for a while so yea and thanks again! also can you help me understand a new questions =/?
questions:
Write a program that inputs a dollar amount and outputs how the amount can be represented using the fewest number of bills and coins. Hint: Use the mod and div commands.
i do not know what mod or div is used for =/ |

That's just a hint. You can see what those operations do at those links -- mod and div |

Thank you, going to try coding it but i don't know how to make it give the least amount of bills and coins for the dollar amount |

Perhaps you should figure that out before trying to code something. I find it helpful to sketch things out on paper, or to work through a specific example.
If I need $26.31, what bills and coins put together such an amount? (How did you figure that out?) |

Think logically how would you do this type of question with pen and paper. Say for an amount of $47.82
Lets assume we are in the Canadian monetary system. The highest legal tender we have is of $100 then $50 then $20 then $10 and lastly $5.
You have a amount of $47.82 you check it and see $100 is too large as well is $50, then you see $20 is smaller and you subtract it from the total; leaving you with 1 x $20 and $27.82 which again you check though starting with the highest you left at which was $20 and it still smaller so you subtract it from the total.
Now you have 2 x $20 and $7.82 which you put though the check again and see that 10 is too large and 5 is the smallest left.
And so on you continue in your head to make chance the computer does the same.
Try to re-create that process in your code. |

ohhh i see ok, but i don't know how to code it does

You compare data.
if var1 > var2 then do bhal
if not then do bhal2
etc. |
