1. Assume that a C program has two files: p1.c and p2.c. On an ia32 server, we compile the code using the Unix Command Line as follows: UNIX> gcc-O1-o p p1.c p2.c In fact, the GCC command calls a series of programs to convert the source code into executable code. First, the C Preprocessor extends the source code, inserts all files specified with the # include command, and extends all the macros specified with the # define declaration. Then, the compil
