MiniC Compiler

A simplified compiler for a subset of the C programming language, built in Java using JFlex and CUP.

✨ Features

• Lexical Analysis with JFlex - Token and identifier recognition
• Syntax Analysis with CUP - Expression and statement parsing
• Support for:
  • Data types: int, double
  • One-dimensional arrays
  • Control structures: if/else, while
  • Arithmetic and logical operators
  • print statements for output

🛠️ Build & Usage

# Compile jflex
jflex scanner.jflex

# Compile cup
java java_cup.MainDrawTree parser.cup

javac *.java

# Run the compiler on a file
java Main bubble.c

📝 Supported Code Example

// Variable and array declaration
double x[5];
int i;

// Initialization
x[0] = 2.5;
i = 0;

// Control structures
while(i < 5){
    if(x[i] > 0){
        print x[i];
    }
    i = i + 1;
}
