what is the size of int in 64-bit machine?

[sahitya v]

in a 16-bit machine size of int is 2bytes and in 32-bit machine size of int is 4bytes.... what is the size of int in a 64-bit machine??

The size of a type is not dependent upon the machine. Rather, it is dependent upon the implementaton of C or C++ that was used to compile the program.

So you have to use sizeof to determine the type size of the implementation that was used to compile the program. For example, a 64-bit Windows machine can execute programs compied both as 32-bit and 64-bit.

64 bit machine has int of 4 bytes.
