这个作业属于哪个课程	福州大学-2023软件工程实践
这个作业要求在哪里	软件工程第二次作业--文件读取
这个作业的目标	掌握文件读取、JSON解析
其他参考文献	单元测试、《git入门》

0、Gitcode项目地址

https://gitcode.net/xxdhd1/project-c

1、PSP表格

PSP	预估耗时（分钟）	实际耗时（分钟）
C++配置Json	10	600
获取Json	60	10
思考	30	30
编写代码	120	120
测试	30	10
得到exe	20	10
总计	270	780

2、功能实现

获取input.txt中每一行命令，对于每个命令都会产生一个编号，不同编号传递到myoutput函数中对应不同的输出模式。
