Using the C/C++ Formatter is simple:
This tool helps you auto-beautify C/C++ code:
• Auto Indentation — Detect code block nesting levels
• Brace Style — K&R (same-line {) or Allman (next-line {)
• Operator Spacing — Add proper spaces around operators
• Blank Line Cleanup — Remove consecutive blank lines
• Preprocessor directives — Keep #include/#define at line start
Note: This tool provides basic formatting without complex AST analysis. All processing is done locally in your browser.
No. Formatting only adjusts whitespace and layout. The code remains functionally identical.
K&R places the opening brace on the same line (if (x) {), while Allman places it on a new line. Both are valid; it's a matter of preference.
Supports basic C/C++ syntax structures including functions, classes, and control flow. For complex nesting, consider using an IDE formatter.
