从网上拷贝了一份比较简单的代码，编译时遇见以下问题：

test_getopt.c:9:35: error: stray ‘\342’ in program
test_getopt.c:9:35: error: stray ‘\200’ in program
test_getopt.c:9:35: error: stray ‘\235’ in program
test_getopt.c:12:3: error: stray ‘\342’ in program
test_getopt.c:12:3: error: stray ‘\200’ in program
test_getopt.c:12:3: error: stray ‘\230’ in program
test_getopt.c:12:3: error: stray ‘\342’ in program
test_getopt.c:12:3: error: stray ‘\200’ in program
test_getopt.c:12:3: error: stray ‘\231’ in program
test_getopt.c:13:4: error: stray ‘\342’ in program
test_getopt.c:13:4: error: stray ‘\200’ in program

说一下，出现此问题的原因是，源代码中存在汉语时的字符，如“”、，等，将其改过来即可！
