在C++程序中迷路'\ 342'

Question

在粘贴一些代码后,我在程序中收到这些错误:

showdata.cpp:66: error: stray ‘\342’ in program
showdata.cpp:66: error: stray ‘\200’ in program
showdata.cpp:66: error: stray ‘\235’ in program
showdata.cpp:66: error: stray ‘\’ in program
showdata.cpp:66: error: stray ‘\342’ in program
showdata.cpp:66: error: stray ‘\200’ in program
showdata.cpp:66: error: stray ‘\235’ in program
showdata.cpp:67: error: stray ‘\342’ in program
showdata.cpp:67: error: stray ‘\200’ in program
showdata.cpp:67: error: stray ‘\235’ in program
showdata.cpp:67: error: stray ‘\’ in program
showdata.cpp:67: error: stray ‘\342’ in program
showdata.cpp:67: error: stray ‘\200’ in program
showdata.cpp:67: error: stray ‘\235’ in program

以下是导致错误的两行.

size_t startpos = str.find_first_not_of(” \t”); 
size_t endpos = str.find_last_not_of(” \t”); 

如何解决这个问题？

Answer 1

符号”不是".这些被称为"智能引号",通常可以在丰富的文档或博客中找到.

Answer 2

线条

 size_t startpos = str.find_first_not_of(” \t”); 
 size_t endpos = str.find_last_not_of(” \t”); 

有一些"特殊"的双引号,请尝试以下方法:

 size_t startpos = str.find_first_not_of(" \t"); 
 size_t endpos = str.find_last_not_of(" \t");
