I'm having run time error in addStu function when trying to read data from input file to binary tree, is there anything wrong with the format or pointer usage? This is my code for reading file: <pre><code>#include <stdio.h> #include <stdlib.h> #include <ctype.h> #include "BST_ADT.h" // Structure typedef struct { char* name; char* market; char* initial; float stock; }STUDENT; // Prototype Delarations void addStu (BST_TREE* list); //void deleteStu (BST_TREE* list); //void findStu (BST_TREE* list); //void printList (BST_TREE* list); //int compareStu (void* stu1, void* stu2); //void processStu (void* dataPtr); int main (void) { // Local Definitions BST_TREE* list; // Statements list = BST_Create(compareStu); addStu(list); deleteStu(list); findStu (list); printList(list); return 0; } /*===================== addStu =========================*/ void addStu (BST_TREE* list) { // Local Declarations STUDENT* stuPtr; FILE* fp; char fileName[25]; char buffer [100]; // Statements stuPtr = (STUDENT*)malloc (sizeof (STUDENT)); printf("Enter the file name: "); gets(fileName); fp = fopen(fileName, "r"); if(fp == NULL) { printf("Error cannot open the file!\n"); exit(101); } while(fgets(buffer, 100, fp) != NULL) { if (!stuPtr) printf("MEmory overflow!\n"), exit(101); sscanf(buffer, "%s %s %s %f", stuPtr->name, stuPtr->market, stuPtr->initial, &(stuPtr->stock));; } // end while BST_Insert(list, stuPtr); } //addStu </code></pre> this is my input: <pre><code>Microsoft Corporation; NASDAQ MSFT 259.94B Yahoo!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
