I have 2 Function :

void AddElements(TreeType& tree, int info[], int fromIndex, int toIndex)

{ int midIndex;

if (fromIndex

void MakeTree(TreeType& tree, int info[], int length) // Creates a binary tree from a sorted array. { tree.MakeEmpty(); AddElements(tree, info, 0, length-1); }

So I want to read int array from text file and put to info[] like this: content text file: IsEmpty

PutItem P

PutItem F

PutItem S

PrintTree

MakeTree -100, -97 -23 -44 -69 -67 -55 -67 -9 -13 -9 -3 8 32 59 70 22 28 33 41 89 79 24 39 85

invoke in main.CPP :

else if (command == "MakeTree") {

int length=25; int ar[length]; for(int i=0;i inFile>>ar[i];

}

tree.MakeTree(tree,ar,length);

}

But I get an error, anybody can help me for doing this assignment?
