Sizeof data types
I am getting output for below code as 8 4 4 in gcc version 4.5.2. Can anyone explain why I am getting this output ?

Because on your system, a floating point number is 8 bytes, an integer is 4 bytes, and a character is 4 bytes.

How can integer and char can take same byte size ?

In C, character constants are integers, but in C++, character constants are chars.
If you compiled this as a C++ program, you would most likely see 8 4 1 as the output.

size of a double
sizeof an int

In C a character constant in an int not a char.

you can get value of int but not get value of character.

What does that mean? A character constant is an int, and a char is an integer type so also has a "value".
