CMSC 104, Lecture 0118 Hardware & Software Needs Do I need my own computer? oNo, but it is more convenient for you. If I have my own computer, can I use it? oSure, but you will use it mostly to log in to your GL account or for word processing. Do I need a C Compiler? oNo, and you probably shouldn’t buy one. All final programming should be done in your GL account. => the CD in your textbook provides a free C/C++ compiler that can be used to test your programs on your home PC
