// Accessing Characters and Length
#include <iostream>
#include <string>
using namespace std;

int main() {
    // Step 1: Declare a sample string
    string myString = "Example";

    // Step 2: Get the length of the string
    cout << "String: " << myString << endl;
    cout << "Length: " << myString.length() << endl; // Or myString.size()

    // Step 3: Access characters using [] operator
    cout << "First character: " << myString[0] << endl;   // 'E'
    cout << "Last character: " << myString[myString.length() - 1] << endl; // 'e'

    // Step 4: Access characters using at() method (provides bounds checking)
    cout << "Character at index 2 (at()): " << myString.at(2) << endl; // 'a'

    // Step 5: Iterate through the string using a for loop
    cout << "Characters in string: ";
    for (int i = 0; i < myString.length(); ++i) {
        cout << myString[i] << " ";
    }
    cout << endl;

    return 0;
