Namespaces

This example shows how to use namespaces to organize code and avoid naming conflicts.

cppCopy code#include <iostream>

namespace Math {
    int add(int a, int b) {
        return a + b;
    }
}

namespace StringUtils {
    void printHello() {
        std::cout << "Hello, World!" << std::endl;
    }
}

int main() {
    std::cout << "Sum: " << Math::add(3, 4) << std::endl; // Output: Sum: 7
    StringUtils::printHello(); // Output: Hello, World!
    return 0;
}
