实现通讯录
要求具体完成
1. Makefile2.main.c3. tongxunlu.h3. tongxun.c
实现通讯录 要求1.用makefile管理文件
2.各个子功能
a:添加用户(连续添加)
b:查看用户(按照姓名的首字母排序)
c:搜索用户(两种方式：id,用户名)
d:删除用户信息
e:修改用户信息
3.自己封装字符串处理函数
具体完成 1. MakefileTARGET ?= run OBJS := main.o tongxun.o CC := gcc CFLAGS := -c -o CFLAGSs := -o $(TARGET):$(OBJS) $(CC) $(OBJS) $(CFLAGSs) $(TARGET) main.o:main.c $(CC) main.c $(CFLAGS) main.o func.o:func.c $(CC) tongxun.c $(CFLAGS) tongxun.o clean: rm -rf $(OBJS) $(TARGET)2.main.c
