Hallo,
bei folgendem Programm erkennt mein Compiler die Deklarationen diverser Methoden nicht, z.B. print(). Kann mir jemand erklären warum? Danke.
| C++: |
#include<iostream>
#include<time.h>
using namespace std;
template <class T>
class MergeArray{
private:
T *mArray;
int ALaenge;
int AIndex;
public:
MergeArray(int inLaenge = 50){
mArray = new T[inLaenge];
ALaenge = inLaenge;
AIndex = 0;
}
void print();
void insert(string);
void mergeSort(int, int);
};
template <class T>
void MergeArray::print(){
for(int i=0; i<ALaenge; i++)
cout << mArray[i] << "\t";
cout << endl;
}
template <class T>
void MergeArray::insert(T inString){
if(AIndex <= ALaenge)
mArray[AIndex++] = inString;
else
cout << "Das Array ist voll!" << endl;
}
template <class T>
void MergeArray::mergeSort(int iLeft = 0, int iRight = ALaenge-1){
const int Middle = (iLeft + iRight) / 2;
const int NrElements = iLeft - iRight + 1;
if(iLeft < Middle) mergeSort(iLeft, Middle);
if(Middle + 1 < iRight) mergeSort(Middle+1, iRight);
T* tmpArr = new T[NrElements];
for(int i=0; i<NrElements; i++)
tmpArr[i] = mArray[iLeft+i];
int itmpL = 0;
const int tmpMiddle = Middle - iLeft + 1;
int itmpR = tmpMiddle;
for(int i=iLeft; i<=iRight; i++){
mArray[i] = tmpArr[itmpL] < tmpArr[itmpR] ? tmpArr[itmpL++] : tmpArr[itmpR++];
if(itmpL == tmpMiddle){
for(++i; i <= iRight; i++)
mArray[i] = tmpArr[itmpR++];
return;
}else if(itmpR == NrElements){
for(++i; i <= iRight; i++)
mArray[i] = tmpArr[itmpL++];
return;
}
}
delete []tmpArr;
}
int main(){
MergeArray<string> mA;
srand(time(NULL));
for(int i=0; i<50; i++)
mA.insert(rand() % 100 + 65);
mA.print();
mA.mergeSort();
mA.print();
system("pause");
return 0;
}
