C++ Lessons

Source files, folders, file extensions, and how C++ lesson materials are stored.

Create a small program with main, cout, and return 0.

Compile a .cpp file into an .exe file using Clang++.

Run the compiled C++ program and read its output in the command prompt.

Learn how to read simple C++ compiler errors and fix one problem at a time.

Prove the full source file, Clang++, EXE, and CMD output workflow from one simple task package.

Build the visible C++ program skeleton: include line, main, braces, statements, and return 0.

Learn that a C++ program is made from statements and that simple statements usually end with semicolons.

Use visible output as the first proof that the C++ program ran correctly.

Print exact text labels with std::cout.

Use newline characters so C++ output stays readable line by line.

Add simple comments that explain the code for humans.

Create simple integer variables and print their values.

Print integer values clearly with std::cout and readable labels.

Create and print more than one variable in the same program.

Use readable variable names that explain what the value means.

Connect variable names to practical values like temperature and score.

Use int, char, and float in one small beginner program.

Store and print one-character values with char.

Compare whole-number and decimal-number values in C++.

Print the same decimal value with different precision settings.

Inspect how many bytes common data types use.

Match real values like score, grade, and temperature to suitable data types.

Use long and double in one beginner-friendly program.

Convert one value between basic types and compare the printed result.

Use const values when data should stay fixed.

Understand operators as symbols that act on values and variables.

Practice add, subtract, multiply, and divide in one small report.

Use = and short update forms like += for small value changes.

Compare values and print true or false style results.

Combine conditions with AND, OR, and NOT checks.

Store and print true/false style values with bool.

See how brackets change expression order and final results.

Run a code block only when a condition is true.

Choose between two result paths from one condition.

Check several conditions in order and stop on the first match.

Use the ternary operator as a short form for choosing one of two values.

Select one branch from fixed integer cases.

Repeat code while the loop condition stays true.

Run the loop body first and check the stop condition after it.
