A cross-platform IDE for C and C++


A power tool
for a power language

Who wouldn’t like to code at the speed of thought while the IDE does all the mundane development tasks for them? But is that really possible for a tricky language like C++, what with its modern standards and heavily templated libraries? Why, yes, yes it is! See it to believe it.

Smart C and C++ editor

Code assistance

Read and write code effectively with an editor that deeply understands C and C++. Have completion results filtered by type in Smart Completion. Use Breadcrumbs to track your location inside the hierarchy of scopes. Gain insight into function calls thanks to parameter name hints. Find the context usages of a symbol or simply jump to it by typing its name. CLion will even make sure your code conforms to coding guidelines, including formatting, naming, and more.

Code generation

Generate tons of boilerplate code instantly. Override and implement functions with simple shortcuts. Generate constructors and destructors, getters and setters, and equality, relational, and stream output operators. Wrap a block of code with a statement, or generate a declaration from a usage. Create custom live templates to reuse typical code blocks across your code base to save time and maintain a consistent style.

Safe refactoring

Rename symbols; inline a function, variable, or macro; move members through the hierarchy; change function signatures; and extract functions, variables, parameters, or a typedef. Whichever automated refactoring you use, rest assured CLion will safely propagate the appropriate changes throughout your code.

Quick Documentation

Inspect the code under the caret to learn just about anything: function signature details, review comments, preview Doxygen-style documentation, check out the inferred type for symbols lacking explicit types, and even see properly formatted final macro replacements.
