C++ Cheatsheet

This comprehensive reference guide covers essential C++ programming concepts, structures, and syntax to help developers quickly build, debug, and optimize applications.

Key Features & Topics

Basics & Syntax: Includes standard boilerplate code structures, console input (cin), and output (cout) operations.

Data Types & Escape Sequences: Details primitive data types (such as int, float, char, double, and bool) alongside standard escape sequences.

Strings & Math Functions: Summarizes string manipulation techniques (concatenation, length, and access) and built-in math functions from <cmath> like sqrt, pow, ceil, and floor.

Control Flow & Loops: Explains decision-making syntax (if-else, ternary operators, switch) and looping constructs (while, do-while, for, along with break and continue).

Memory Management: Covers references and pointers, including dereferencing and null pointer usage (nullptr).

Object-Oriented Programming (OOP): Highlights classes, objects, constructors, inheritance, and polymorphism via virtual functions.

Advanced Concepts: Features file handling streams (ifstream, ofstream), exception handling blocks (try, catch), namespaces, templates, and Standard Template Library (STL) components.
