idnefier endl in undefince

#include <iostream>

int main() {
    std::cout << "Hello, World!" << std::idnefier; // Error: 'idnefier' was not declared in this scope
    std::cout << std::endl; // Output: Hello, World! followed by a new line

    return 0;
}

Explanation: 1. Include the necessary header file for input and output operations (iostream). 2. Define the main function, which serves as the entry point of the program. 3. Use std::cout to output the string "Hello, World!" to the console. 4. Intentionally introduce an error by misspelling 'identifier' as 'idnefier' to demonstrate an undefined identifier error during compilation. 5. Use std::cout again to output the std::endl manipulator, which adds a new line to the console output. 6. Return 0 to indicate successful program execution.
