We know in Java or in C# onecan trim a string. Is there any function which can do th same?

For example:

...
...
string s1;
...
...

in run time, s1 has a value of "hello world   ". I want to trim the spaces to have "hello world". Surely there many methods to do this. But I want a simple way.

s1.erase ( s1.find_last_not_of (" ") + 1 ) ;

You can add more characters to the " " string, which specifies which characters to trim off the end. If you for example also want to trim tabs, use " \t".

BTW: If you also want to trim the string on the left side, there is also the find_first_not_of() method.
