2. Consider the following makefile. The files block2.c, block2.h, block1.c. block1.h and main.c all reside in the same directory as the makefile. There are no other files in this directory. CC=gcc CFLAGS=-C - Wall all: final final: main.o block1.o block2.o $(CC) main.o block1.o block2.o -o final main.o: main.c $(CC) $(CFLAGS) main.c block1.o: blockl.c block1.h $(CC) $(CFLAGS) block1.c block2.o: block2.c block2.h $(CC) $(CFLAGS) block2.c clean; rm -f final *.0 a) Suppose I run make in the above directory. List the files that are created? Assume that all the C files compile correctly without errors. b) Suppose I modify blockl.c after running step a). Assume that after the modifications, blockl.c still compiles correctly. If I now run make, which file(s) get re-generated? Why is it that all files from the previous step are not re- generated? c) Suppose I run touch main.c and execute make main.o, which new file/files will be generated? 2.
