About C/C++ Formatting
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 computation happens on your device — Operator spacing, Remove extra blank l and other inputs stay in your browser.
Frequently Asked Questions (FAQ)
Will formatting change my code's logic?
No. Formatting only adjusts whitespace and layout. The code remains functionally identical.
What's the difference between K&R and Allman brace styles?
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.
Which syntax features are supported?
Supports basic C/C++ syntax structures including functions, classes, and control flow. For complex nesting, consider using an IDE formatter.
