1) 的行为就像UnformattedInputFunction, 除了input.gcount()不会受到影响.在构造和检查岗哨对象的, 执行以下操作: 1) 调用str.erase() 2) input并把它们添加到str的字符提取出来, 直到发生以下情况之一中列出的顺序进行检查 a) 上input文件结束的条件, 在这种情况下, getline套eofbit和回报. b) 下一个可用的输...
you can use the C++ string getline() function to read lines into strings void ReadDataFromFileLBLIntoString() { ifstream fin( " data.txt " ); string s; while ( getline(fin,s) ) { cout << " Read from file: " << s << endl; } } // 带错误检测的读取方式 // Simply evaluating ...

1) 表现为无格式输入函数 (UnformattedInputFunction) ,除了不影响 input.gcount() 。构造并检查 sentry 对象后,进行下列操作: 1) 调用str.erase() 2) 从input 释出字符并后附它们到 str ,直至发生下列条件之一(按顺序检查): a) input 上的文件尾条件,该情况下, getline 设置eofbit。 b) 下个可用输入字符...
当你在C++中遇到“no matching function for call to 'getline'”的错误时,这通常意味着getline函数的调用与任何已定义的getline函数重载都不匹配。以下是一些可能的原因和解决方案: 确认getline函数的调用上下文: getline常用于从文件或标准输入读取数据。确保你调用的上下文是正确的。例如,如果你试图从文件读取,确保...

The following example demonstrates how to use thegetlinefunction to read user input, and to process a stream line by line, or by parts of a line using thedelimparameter. Run this code #include <iostream>#include <sstream>#include <string>intmain(){// greet the userstd::stringname;std::...
Conclusion In this article, we learned about using std::getline() in C++. We also look at some examples which illustrate the power, and pitfalls of this function. References cppreference.com page
Edit & run on cpp.sh Oct 17, 2012 at 10:03pm doug4(1538) alx101 suggested that you post your error messages. That would be helpful. But in the interim, lines 7 - 20 need to be in a function somewhere. I'm sure this is giving you errors. Actually, lines 29 to the end are ...
