The document contains code snippets in C++. The snippets demonstrate basic C++ programs that calculate area and circumference of a circle, perimeter and area of a rectangle, average of marks, printing text, functions to check even and odd numbers in an array, functions to return the larger of two numbers, and a function to print a line of a character.
