More about sizeof() operator

Question:
I'm using the sizeof() operator to find the length of my integers just like the Q&A section said, but it consistently returns a 4 regardless of integer length. What could be causing an error like this?

Answer:
I'm more puzzled trying to determine exactly what it was you were expecting sizeof() to do.

sizeof() returns the number of bytes a variable, or variable type, occupies. Your particular compiler apparently implements long integers, which each take up 4 bytes.

This is normal behavior.
