一個超好用的c++網站:http://www.cplusplus.com/reference/string/string/erase/
一、string類的函數
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.
