# PsycheC Type Inference

This Space provides a web interface to [PsycheC](https://github.com/ltcmelo/psychec), a compiler frontend for the C programming language that can infer missing type declarations.

## What it does

PsycheC analyzes C source code and:
- Infers types for undeclared identifiers
- Generates a header file (`_gen.h`) with the inferred type declarations
- Produces a fixed C file (`_fixed.c`) that includes the generated header

## Usage

1. Paste your C code in the input text area
2. Click "Run Type Inference"
3. View the generated header and fixed C code in the output tabs

## Example

Input:
```c
int main() {
    x = 10;
    y = foo(x);
    return y;
}
```

The tool will infer the types of `x`, `y`, and `foo` and generate appropriate declarations.
