# MiniC to UCode Compiler
### About project
This is a MiniC compiler project using JAVA Antlr which generates UCode of IR.

### Contents
#### Simple pointer function
``` C
void swap(int *a, int *b) {
    int temp;
    temp = *a;
    *a = *b;
    *b = temp;
}

void main() {
    int a = 5;
    int b = 10;
    swap(&a, &b);
    write(a);
    write(b);
}
```

#### Compile error detection
> - Use of undeclared identifier<br>
> - Non-void function should return a value<br>
> - Void function should not return a value<br>
> - Initializing 'int' with an expression of incompatible type 'void'<br>
