string
Read and dicard any leading whitespace(e.g., spaces, newline, tabs)
It then reads characters until the next whitespace character is encountered
string 读取终止时将whitespace留在输入流中
getline
read line at time until end-of-file
whenever getline encounters a newline ,even if the first character in the input
it stop reading input and returns
getline 读取终止并丢弃换行符(换行符从输入流中去掉并不储存在string对象中)
在使用st.size()统计字符串个数时,包括换行符"a/n" st.size = 2;
NOTE
string comparisons are case-sensitive the upper- and lowercase versions of a letter a different characters
Every uppercase letter is less than any lowercase letter.
The relational operators compare strings using the same trategy as in a dictionary
If two string have different length and if every character in the shorter string is equal to the corresponding character
of the longer string, then the shorter string is less than the longer one.
If the characters in two string differ, then we compare them by comparing the first character at which the string differ.
As an example:
string substr = "Hello";
string phrase = "Hello World";
string slang = "Hiya"
substr < phrase true
slang > phrase true
