写一个程序实现以下命令行功能
foo [-h] [-pfs] [-i filename] [-o filename]
USAGE EXAMPLES:
$ ./foo -h
Usage: foo [-h] [-pfs] [-i filename] [-o filename]
-h Show the help message.
-p Only report on tests which passed.
-f Only report on tests which failed.
-s Only report summary.
-i [filename] Use the specified file as the input data.
-o [filename] Output the summary data to the specified file.
除了有－i参数将从文件获得数据，其他正常情况都需要从命令行输入参数，格式大概是：
Enter a test suite name: suite1
Enter a test name: test1
Enter a test summary for "suite1/test1": Test information for suite1/test1.
Enter a test result for "suite1/test1": PASS
Add another test: y
如此循环下去，直到你敲了n退出。
