C# For Python Programmers

Syntax and core concepts

Basic Syntax

• Single-line comments are started with //. Multi-line comments are started with /* and ended with */.

• C# uses braces ({ and }) instead of indentation to organize code into blocks. If a block is a single line, the braces can be omitted. For example,

###########################################################################
#
## @file database.py
#
###########################################################################

import sqlite3

Effective Modern CMake

Getting Started

For a brief user-level introduction to CMake, watch C++ Weekly, Episode 78, Intro to CMake by Jason Turner. LLVM’s CMake Primer provides a good high-level introduction to the CMake syntax. Go read it now.

After that, watch Mathieu Ropert’s CppCon 2017 talk Using Modern CMake Patterns to Enforce a Good Modular Design (slides). It provides a thorough explanation of what modern CMake is and why it is so much better than “old school” CMake. The modular design ideas in this talk are based on the book [Large-Scale C++ Software Design](https://www.amazon.de/Large-Scale-Soft
