1. (60 points) Modify Project 9 program so that the program is split into three source files and two header files. 1) Put all functions related to operations on the list of players into equipment.c 2) Create a header file named equipment.h that contains struct equipment declaration and prototypes for the functions in equipment.c. The header file should enclose the contents of the header file in an #ifndef- # endif pair to protect the file. 3) Put the readline function is in a separate file named readline.c. 4) Create a header file named readline. h that contains a prototype for the read line function. The header file should enclose the contents of the header file in an #ifndef-#endif pair to protect the file 5) group equip.c contains the main function. 6) Include appropriate header files in the source files. 2. (40 points) Write a makefile to build the roster program on circe. The makefile should co ntain the following rules: 1) Build readline.o by compiling readline.c 2) Build equipment.o by compiling equipment.c 3) Build group_equip.o by compiling group equip.c 4) Build group equip by linking readline.o, equipment.o, and group_equip.o Each rule should include the name of the target file, dependencies among files, and the command to be executed. The makefile should name the executable file for the program roster Before you submit: 1. (part I) Compile with the following command and test with try_ equip gcc -Wall equipment.c readline.c group equip.c ./try equip 2. (part 2) Be sure your makefile contains the information necessary to build the roster program. Test your makefile: make group equip . group equiD 1.
