Array

**abdullahmert** · 12-24-2011

CAN YOU SOLVE THİS QUESTİONS ???

a) Write a C program that will read the data shown below into an array.
b) Calculate the AVERAGE score using the following formula:
AVERAGE[STUDENT]=0.15*Qz1+0.15*Qz2+0.15*Hw1+0.15*Hw1+0.40*MT
c) Round the AVERAGE score to the nearest ten’s possible (NEARESTTENS). For example, if a students grade is 12, round it to 10. If a students grade is 16, then round it to 20.
d) Find the mode, mean and median of the AVERAGE result shown above.
e) Draw the histogram of NEARESTTENS points scored by the students.

Christmas Homework! I see they gave you some stuff to study , how about you try first , post some code and we tell you what is the problem with your code ... CAN YOU TRY ?

**Adak** · 12-24-2011

It's VERY much up to you to get your program started - then if you run into a problem, post back and tell us what the problem is - and we'll try to help. The more detailed you are about the problem, the quicker we can give that assistance.

We won't take your assignment, and do it on your request, however.

**abdullahmert** · 12-24-2011

I tried but it has some error..

**fdrake** · 12-24-2011

post your code here and we will give you directions or correct it for you

**abdullahmert** · 12-24-2011

I am not sending I dont understand..

**abdullahmert** · 12-24-2011

how will I send the program???

**rags_to_riches** · 12-24-2011

Copy and paste it into a post within code tags, as in Announcements - General Programming Boards

**Adak** · 12-24-2011

Silly Hogwart's freshman - by owl, of course!

Click on the "Reply to Thread" button. In the advanced editor page, put your message, and then click on the # icon at the right top side of the icon's in the "toolbar" header.

You'll see two [code ][/code ] tags ( but without the space before the ] )
and your cursor will be sitting right between them.

Just paste your code in there, without moving your cursor from where it was put by the editor.

and then press the "Submit Reply" button.

That way (using the code tags), your code will keep it's correct indentation (which I hope you have given it), and be MUCH easier to read, study, and find the errors if any.

Don't hold your breath!

From what we've seen, this poster is nothing more than a leecher. He will nothing other than try and get you to do everything for him and will make no attempt to do this himself.

If you even think of throwing this guy a bone, first consider if you would ever want him to be your superrior in the workplace.

I cringe at the fact that this reply will bump the thread.

With code tags -- AND int main(void) with return 0 -- AND good indentation -- well done!

The marks need to be either double or floats, rather than ints. If the mark is 70.25, is it OK to have it in the array as 70,25 - with the comma instead of the decimal point?

Any compiler errors or problems, so far?

You didn't ask any questions.

Yay, finally!
Good okay, what's the problem?
