Dynamic Text

C++ Strings

The modern std::string class from the <string> header. It handles memory automatically and provides rich features for text manipulation.

BASIC OPERATIONS

string s1 = "Hello";
string s2 = "World";

string s3 = s1 + " " + s2; // Concatenation
cout << s3.length();       // 11
cout << s3[0];             // 'H' (Access)

DYNAMIC SIZE

Grows and shrinks automatically as you add or remove characters.

SAFE ACCESS

Use s.at(i) for bounds-checked access; it throws an error if the index is invalid.

STRING VS CHAR ARRAY

Prefer std::string over C-style character arrays. It's safer, more flexible, and integrates better with STL algorithms.
