I'm currently in an Intro C++ class, and I'm learning about Strings and Member Functions of them.
I have questions that are like this:
Assume that name is a variable of type string that has been assigned a value. Write an expression whose value is a string containing the first character of the value of name . So if the value of name were "Smith" the expression's value would be "S".
or
Assume that name is a variable of type string that has been assigned a value. Write an expression whose value is a string containing the last character of the value of name . So if the value of name were "Smith" the expression's value would be "h".
or
Assume that word is a variable of type string that has been assigned a value. Write an expression whose value is a string consisting of the last three characters of the value of word . So if the value of word were "biggest" the expression's value would be "est".
I know things like name[0] and name[name.length() - 1], but I don't know how to turn those into a string in one expression. I've been looking for a table or list of member functions that can help me do this, but I'm stuck. Any directions or aid would be great.
(Apologies if this should go into general programming)
