Basics Summary

In this lesson we learned the basic concepts of C++:

1. Basic structure of a C++ program:
   • #include <iostream> for input/output operations
   • The main() function as the program's entry point
   • Curly braces {} to denote code blocks
2. Text output using:
   • std::cout for output
   • The << operator for output direction
   • std::endl to end the line
3. Multiple ways to output multiple lines:
   • Multiple std::cout commands
   • One std::cout command with multiple std::endl
4. Comments for code documentation:
   • Single-line comments //
   • Multi-line comments /* */

In the next lesson we will cover variables and data types in C++!
