c/c++的常用函数和STL使用

一个超好用的c++网站：http://www.cplusplus.com/reference/string/string/erase/

一、string类的函数

1.string& erase (size_t pos = 0, size_t len = npos);

pos：

Position of the first character to be erased.
If this is greater than the string length, it throws out_of_range.
Note: The first character in str is denoted by a value of 0 (not 1).
len：

Number of characters to erase (if the string is shorter, as many characters as possible are erased).
A value of string::npos indicates all characters until the end of the string.
