Learn C++ Step by Step

Example: Vector Operations

#include <iostream>
#include <vector>
#include <algorithm>

int main() {
    // Create and initialize a vector
    std::vector<int> numbers = {5, 2, 8, 1, 9};
    
    // Sort the vector
    std::sort(numbers.begin(), numbers.end());
    
    // Print sorted numbers
    std::cout << "Sorted numbers: ";
    for (const auto& num : numbers) {
        std::cout << num << " ";
    }
    std::cout << std::endl;
    
    // Find an element
    auto it = std::find(numbers.begin(), 
                       numbers.end(), 8);
    
    if (it != numbers.end()) {
        std::cout << "Found 8 at position: "
                  << (it - numbers.begin());
    }
    
    return 0;
}

// Output:
// Sorted numbers: 1 2 5 8 9
// Found 8 at position: 3
