##Requiredpublicfunctionalities

###construction

####3ArgumentConstructor

```C++

Stats(unsignedcolumnWidth=15,

unsignednoOfColumns=4,

unsignedprecision=2);

```

-columnWidth:widthofeachcolumnincharacters

-noOfColumns:numberofcolumnstodisplaythenumbersin

-precision:numberofdigitsafterthedecimalpointforeachnumber

Inthiscase,the"**Stats**"objectisnottiedtoanyfileontheharddriveandisempty.

####4ArgumentConstructor

```C++

Stats(constchar*filename,

unsignedcolumnWidth=15,

unsignednoOfColumns=4,

unsignedprecision=2);

```

Sameasthepreviousconstructor,butinthiscase,ifthefilenameargumentisnotnullandissuccessfullyopened,thenumbersinthefilewillbeloadedintothe**Stats**object.

####CopyConstructor

Copyinga**Stats**objectshouldbedonesafelyanddoingsoitshouldalsocopythedatafileontheharddisk.Thenewfilenameshouldbethesameastheoriginalfilewithanadded**"C_"**prefix.

###Operatoroverloads

####Copyassignment

Assigninga**Stats**objecttoanothershouldbedonesafelyandthecontentofthetargetfileshouldalsobeoverwrittenbythesourcefile.

####Indexoperatoroverloads

```C++

double&operator[](unsignedidx);

```

Returnsthereferenceofthenumberatidxindex.Iftheindexexceedsthesizeofthearray,itshouldloopbacktothebeginning.Forexample,ifthearraysizeis10,index10willbethereferenceoftheelementatindex0andindex11willbethereferenceoftheelementatindex1.

Ifthe**Stats**objectisempty,itshouldreturnthereferenceofadummydoublemembervariable.

```C++

doubleoperator[](unsignedidx)const;

```

Returnsthevalueofthenumberatidxindex.Iftheindexexceedsthesizeofthearray,itshouldloopbacktothebeginning.Forexample,ifthearraysizeis10,index10willbethevalueoftheelementatindex0andindex11willbethevalueoftheelementatindex1.

Ifthe**Stats**objectisempty,itshouldreturnzero.

###Booleantypeconversionoverload

If**Stats**iscastedtoboolean,itshouldreturntrueonlyifitisnotempty.Otherwise,itshouldreturnfalse.

###Methods(Membervariables)

####sort()

```C++

voidsort(boolascending);

```

Sortsthenumbersinascendingordescendingorder.

####size()

```C++

unsignedsize()const;

```

returnsthenumberofnumbersinthe**Stats**object.

####name()

```C++

constchar*name()const;

```

returnsthenameofthefiletiedtothe**Stats**object.

####occurrence()

```C++

unsignedoccurrence(doublemin,doublemax,std::ostream&ostr=std::cout);

```
