Strings in C++ can be handled using two primary approaches:

1️⃣ C-Style Strings

• These are character arrays ending with a null character (\0).

Example:

char str[] = "Hello";

• Common operations:
  • strlen(str): Get the length of the string (from <cstring>).
  • strcpy(dest, src): Copy one string to another.
  • strcmp(str1, str2): Compare two strings.

2️⃣ std::string (Preferred in Modern C++)

• Provided by the <string> library.
• Easier to use and safer than C-style strings.

Example:

#include <iostream>
#include <string>

int main() {
    std::string greeting = "Hello, World!";
    std::cout << greeting << std::endl;
    return 0;
}

Features:

• Dynamic size management.
• Member functions like .length(), .substr(), .find(), .append(), etc.
• Operator overloading (e.g., + for concatenation).
