String assignment and manipulation

String Assignment

string s1;                // default constructor, S1 is empty string string s1 (S2);            // Initialize S2 to a copy of S1 string S3 ("value");        // initializes S3 to a copy of a string literal string S4 (n,'C');        // Initialize S4 to n copies of character ' C '

String manipulation

S.empty ()    // if S is an empty string, returns True, otherwise trues.size ()    // Returns the number of characters in S s[n]        // returns the character of position N in S, where the position is counted from 0 s1+s2        // S1 and S2 are concatenated into a new string, returning the newly generated string s1=s2        //  Replace the S1 content with a copy of S2 s1==s2        // compare S1 and S2 content, equal returns True, otherwise false
