I am getting errors when trying to compile my program, can anyone help?
Errors are
error C2143: syntax error : missing ')' before 'constant'
error C2143: syntax error : missing ';' before 'constant'
fatal error C1004: unexpected end of file found
Here is my code:

//    declaration of a binary tree with pointers to left and right children//

#include <assert.h>
#include <stdio.h>
#include <stdlib.h>

#define SIZE 9

typedef int DATA;

		a[j] = temp;
	}
	return b;

// send function a, the array to be divided, and b and c, the 2 array pointers

// count total number of nodes

}

// count number of leaf nodes
int count_Lnodes(BTREE root, int cnt)

		cnt = count_Lnodes(root->right, cnt);
		if (root->left == NULL && root->right == NULL) ++cnt;
	}
	return cnt;
}

The place where I am getting the errors is in

BTREE makeTree(int a[], int i, int SIZE);
BTREE new_node();
BTREE init_node(DATA dat1, BTREE par1, BTREE par2);
BTREE insert(BTREE parent, BTREE root, int item);

Don't use preprocessor macros unless you know how the preprocessor works. It's all to easy to forget that it's textual replacement before anything else. So this:

#define SIZE 9
BTREE makeTree(int a[], int i, int SIZE);

Becomes this:

#define SIZE 9
BTREE makeTree(int a[], int i, int 9);

Which is a syntax error. Therefore, you can't use SIZE anywhere except where you want it replaced with 9.

Hi spitfire and Narue, i am doing some work similar to this and i am try to compile your code to study it, but having the erors you are having. Can someone help me out to fix it so that i can run it and study it.
Thanks
