Seg Fault in program when parsing and storing stri

Question

Right now I'm not even getting a seg fault with my program, I'm pretty sure it just runs forever, because when I run the program no output is produced, not even the segmentation fault. Basically what I want my program to do is read in a file of 4 lines. Then we parse the strings using the user created tokenizer function and the already created strtok function. Then I want to make a binary tree out of the commands that are read in. So like I said earlier my program produces no output at the time, but it does compile. I will post the code that I have and the the file that you read in and the sample output. I appreciate the help.

Here is the sample output that was given:

]$ ./a.out commands.dat 
Command: pickup 
Invalid command, please try again 
Command: pickup ball 
Valid command used 
Command: quit 1 
Invalid command, please try again 
Command: load 
Invalid command, please try again 
Command: load bak.sav 
Valid command used 
Command: help
Valid command used
Command: help 2 
Invalid command, please try again 
Command: quit 
Valid command used 

And the file that we read in is as follows:

pickup,2
help,1
quit,1
load,2
