如何将字符串与回车符0x0D进行比较？

Question

将回车符值传递给std :: string函数时遇到了一些麻烦。

std::string parsedWord;
size_t found = str.find_first_not_of(' ');
if (found == std::string::npos) std::cout << "No non-whitespace characters found\n";
    else
        {
            while (str.compare(found, 1, " ") || str.compare(found, 1, 0x0D )
    // The last argument should be a const char*. 
            {
                    parsedWord += str[found]; found++;
            }
        }  

我特意要比较值0x0D，因为在Windows系统上新行是CR LF而其他系统使用不同的类型，我只想检查0x0D

试试这个

while (str.compare(found, 1, " ") || str.compare(found, 1, "\r")
