C Source Analyzer

A C program analysis toolkit with two utilities.
Designed to remove comments and check basic syntax errors in C source files while handling strings, character literals, and non-nesting comments correctly.

---

Features

1. strip_comments

• Removes all C comments (// and /* */) from source files.
• Correctly handles:
  • Quoted strings ("...")
  • Character constants ('a')
  • Escape sequences (\", \', \\)
• Usage:

./strip_comments < input.c > output.c

2. check_syntax

• Checks C programs for rudimentary syntax errors:

  • Unmatched parentheses ()

  • Unmatched brackets []

  • Unmatched braces {}

• Ignores:

  • Strings and character literals

  • Comments and escape sequences

• Usage:

./check_syntax < input.c

Compilation

• Using GCC directly

# Build strip_comments
gcc src/main_strip.c src/lexer.c -o strip_comments

# Build check_syntax
gcc src/main_check.c src/lexer.c src/stack.c -o check_syntax

• Using Makefile

make

Example Usage

• Remove comments from a file

./strip_comments < example_input.c > example_output.c

• Check for basic syntax errors

./check_syntax < example_input.c
