编译方法
1. 补全代码¶
注意代码中有“LAB3”的注释的地方,代码中所有需要完成的地方都有“LAB3”和“YOUR CODE”的注释。同学们可以根据代码中的注释的提示,思考练习中的问题来补全代码。
2. Makefile修改¶
LAB1 := -DLAB1_EX2 -DLAB1_EX3 #-D_SHOW_100_TICKS -D_SHOW_SERIAL_INPUT
LAB2 := -DLAB2_EX1 -DLAB2_EX2 -DLAB2_EX3
LAB3 := -DLAB3_EX1 -DLAB3_EX2
#LAB4 := -DLAB4_EX1 -DLAB4_EX2
3. 编译运行¶
编译并运行代码的命令如下:
补全代码后可以得到如下显示界面(仅供参考)
