• Optimization technique.
• Use for compile time computation when function is called with constants
• Function is called a runtime with invoked with non-constants

• c++20
• Same as constexpr but required to be evaluated at compile time.

• Use std::string over char lists (C strings). Safer to avoid buffer overflows.
• You can turn a std::string (C++ string) into a C string with myCppString.c_str()

Have the compiler infer the type

Used to define a type

• Use std:vector to declare a dynamic array and push_back() to add more elements and the array will be resized as needed.

  std::vector<int> someList(1); // init array with size of 1
  someList[0] = 1;
  someList.push_back(2); // Use push_back to add more items and resize array at runtime
  

Basically each .cpp file can be compiled separately to create .o files which can be linked together to create one executable.

• g++ -c file1.cpp: creates file1.o
• g++ -c file2.cpp: creates file2.o
• g++ my_executable file1.o file2.o: Links the files and creates the executable.
