Bug: variables are printed within [ ]
Description:
When a variable is detected as part of an expression it is printed within [ ]
To Reproduce:
Steps to reproduce the behavior:
public class Main {
public static void main(String[] args) {
int a =3+6;
int b = a+2;
}
}
int main(int argc, char **argv){
int a = 3+6;
int b = [a]+2;
}
Expected behavior:
The translation should be:
int main(int argc, char **argv){
int a = 3+6;
int b = a+2;
}
