    <p>Its me again and making progress... I want to say thanks to everyone who commented on my last question, it was very helpful. I got this to compile so far but having some weird bugs that I can't iron out. </p> <pre><code>void addRecord(){//carries users input data numRecs++;//increments numRecs by 1 struct record library; //this will hold info for user input printf ("Please enter your first name:\n"); fgets(library.fName, sizeof(library.fName), stdin); printf ("Please enter your last name:\n"); fgets(library.lName, sizeof(library.lName), stdin); printf ("Please enter your hometown:\n"); fgets(library.hometown, sizeof(library.hometown), stdin); printf("You entered %s for your first name.\n", library.fName); printf("You entered %s for your last name.\n", library.lName); printf("You entered %s for your hometown.\n", library.hometown); struct record *myNewRecord;//creates a new struct pointer to store all the old data and new data myNewRecord = malloc(numRecs * sizeof(struct record)); //allocates space to fit all old data plus the new struct data if (myNewRecord == NULL) { fprintf(stderr,"Out of memory\n"); } *myNewRecord = library; fprintf(stderr, "You made it here!!\n"); </code></pre> <p>These are the results I get from the terminal.. It looks like the syntax is all correct in the source code but the issue is it skips the first name fgets for some reason. Also, when it prints out it executes a return somehow. Can you guys see whats going on??? P.S. It doesn't do this when I eliminate the switch case and only have addrecord() in the main.</p> <pre><code>ubuntu@ubuntu:~$ ubuntu@ubuntu:~$ gcc lab222.c -o lab222 ubuntu@ubuntu:~$ ./lab222 Please select from the following: 1. Print all records. 2. Print number of records. 3. Print size of database. 4. Add record. 5. Delete record. 6. Print number of accesses to database. 7. Exit. Enter a number 1-7:4 Please enter your first name: Please enter your last name: Don Please enter your hometown: Mega You entered for your first name. You entered Don for your last name. You entered Mega for your hometown. You made it here!! </code></pre>

    2. COYou're calling `scanf()` twice when you ask for the selection from the menu. You also need to do something to read the newline after the selection, otherwise it will be treated as the first input in `addRecord()`.

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.
