Software Installation Engineer Unix

Ques:- Compare the no. of bytes in unix and Dos for long, char, short, int.

Asked In :-

Right Answer:
In Unix, the sizes are typically:
- `char`: 1 byte
- `short`: 2 bytes
- `int`: 4 bytes
- `long`: 4 bytes (on 32-bit systems) or 8 bytes (on 64-bit systems)

In DOS, the sizes are typically:
- `char`: 1 byte
- `short`: 2 bytes
- `int`: 2 bytes
- `long`: 4 bytes

So, the comparison is:
- `char`: 1 byte (both)
- `short`: 2 bytes (both)
- `int`: 4 bytes (Unix) vs 2 bytes (DOS)
- `long`: 4/8 bytes (Unix) vs 4 bytes (DOS)
