this code is giving wrong answer to me i dont know why plz tell me
here is my code

		size = arr[i];
		float *array=NULL;
		array=new float [size];
		for(int j=0;j<size;j++)
		{
			cin>>array[j];
		}
	
		average(array);
	}
	print();
	return 0;

Hi,
The main thing is about Precision Error. Though you get all the correct output but there is some input you get those error. Try to use double instead of float, its a good practice. And one thing is, dont use ".000%", it will come automatically and dont need to store average. Just print the output on the real time, somethink like that :-
"printf("%.3lf%%\n",(double)cnt/(double)tot*100);". Hope it will you help you. Keep posting.

I got this wrong but i already seek it for month didnt found what is the bug :

[c]
#include <stdio.h>

int main()
{
long n,jlhMurid,i,jk,ehm[500],average,nilai;

scanf("%ld",&n);
for (i=0;i<n;i++){
scanf("%ld",&jlhMurid);
nilai=0;average=0;
for (jk=0;jk<jlhMurid;jk++){
scanf("%ld",&ehm[jk]);
average+=ehm[jk];
}
average=average/jlhMurid;
for (jk=0;jk<jlhMurid;jk++){
if (average<ehm[jk])
nilai++;
}
printf("%.3lf%%\n",(double)nilai/(double)jlhMurid*100.00);
}

return 0;
}

There can be as many as 1000 students in a class, but you only reserve memory for 500.
Change it and you'll get AC.

hiks ... thx bro. It's experience ... find it about month

I'm getting a compile error when I run my program... here's the error

In order to get the right precision of the output I am using the "fixed" function found in the iomanip.h library. However the OJ doesn't like it, so I get a compile error, here's my code that's giving me an error and the error message I get from OJ

cout << fixed << setprecision(3) << (100.0 * percentAbove) << "%" << endl;

Here are the compiler error messages:

03546402_24.c: In function `int main()':
03546402_24.c:42: `fixed' undeclared (first use this function)
03546402_24.c:42: (Each undeclared identifier is reported only once
03546402_24.c:42: for each function it appears in.)

--

I'm just posting for some help in formatting the output so it compiles correctly. The compiler at my school accepts it w/o a problem, not sure why OJ doesn't.

Thanks,
Adam P

You should submit your code as C++. This should make it compile without problem

Ciao!!!

CDiMa -

I tried to submit it again making sure I selected C++ as the type of code. I'm still getting the same compile error.

Is there another library I need to include?I'm only using

<iomanip.h>
<iostream.h>

Thanks

I was induced to think that it was submitted as C code by the compiler messages:

Code: Select all

03546402_24.c: In function `int main()':

As you can see the file extension is .c
Is the file extension of your new submission still .c ?

Ciao!!!

Yeah, still saying .c

I triple checked everything and still am getting the error =( is there a way to format the output w/o using the fixed function?

Here are the compiler error messages:

03553475_24.c: In function `int main()':
03553475_24.c:42: `fixed' undeclared (first use this function)

Well, try to drop the .h in your #includes like this:

Code: Select all

#include <iostream>
#include <iomanip>
using namespace std;

I got OJ to accept my code, however I'm getting WA. My code checks out for all of the sample data, it even tests for a case when there are 0 students, outputting that 0.000% are above average. Are there any other strange cases that I need to account for?

OJ Board

10370 - Above Average

Hey man thanx

10370 above average plz help me out

10370 above average i m in great trouble plz help me

10370 WA Why ???

Thx
