Why is size of int 4 bytes?

So the reason why you are seeing an int as 4 bytes (32 bits), is because the code is compiled to be executed efficiently by a 32-bit CPU. If the same code were compiled for a 16-bit CPU the int may be 16 bits, and on a 64-bit CPU it may be 64 bits.

What is the size of INT in 32-bit?

For example, in 16-bit machines, sizeof (int) was 2 bytes. 32-bit machines have 4 bytes for int. It has been considered int was the native size of a processor, i.e., the size of register. However, 32-bit computers were so popular, and huge number of software has been written for 32-bit programming model.

How many bytes does an int take in C?

Based on how a compiler is implemented, it can take either 2 bytes or 4 bytes. An int is guaranteed to have a minimum range from -32768 to 32767, i.e, from – (2^16) to (2^16)–1 which means it must occupy a minimum of 16 bits or 2 bytes. But again, based on implementation, an int can have even a higher range and thus take up more space.

What is the size of an integer in bytes?

Nowadays, it’s most often 4 bytes on a 32-bit as well as 64-bit systems. Still, using sizeof (int) is the best way to get the size of an integer for the specific system the program is executed on. EDIT: Fixed wrong statement that int is 8 bytes on most 64-bit systems.
