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...
cin.getline()函数是处理数组字符串的,其原型为cin.getline(char* , int),第一个参数为一个char指针,第二个参数为数组字符串长度。getline(cin... 我们用cin.get(c)处理cin丢弃的换行符之后getline就可以正常等待用户输入下面来看看getline怎么处理输入hello之后的换行符可以看到第二个getline可以正常输入说明第一个...
ch = cin.get();//把之前输入的回车符号滤去gets(array4);//The gets function reads a line from the standard input stream stdin and stores it in buffer.//The line consists of all characters up to and including the first newline character ('\n').//gets then replaces the newline charact...

A global function with the same name exists in header <string>. This global function provides a similar behavior, but with standard C++stringobjects instead of c-strings: seegetline (string). Parameters s A pointer to an array of characters where the string is stored as a c-string. ...

an intervening call to a file positioning function, unless the inputoperation encounters endof-file. Opening (or creating) a text filewith update mode may instead open (or create) a binary stream in someimplementations. 所以只要在matrix = create_matrix(file);前面加上file.seekg(0, std::ios_...
