Is int always 4 bytes in C?
Nowadays in most of compilers int is of 4 bytes. If you want to check what your compiler is using you can use sizeof(int) .
Is an int one byte?
The DataBlade API ensures that these integer data types are one byte on all computer architectures. There is no corresponding SQL data type for one-byte integers….One-byte integers.
| DataBlade API one-byte integer | Description |
|---|---|
| mi_sint1 | Signed one-byte (eight bits) value |
| mi_int1 | Unsigned one-byte (eight bits) value |
Can int be 8 bytes in C?
There is nothing stopping compilers from using an 8-byte int other than the fact that it would probably break tons of existing code. For the last 20 or so years, people have assumed that an int is 4 bytes long (on x86 and amd64 CPUs, at least).

What is int size in C?
The minimum size for char is 8 bits, the minimum size for short and int is 16 bits, for long it is 32 bits and long long must contain at least 64 bits. The type int should be the integer type that the target processor is most efficiently working with. This allows great flexibility: for example, all types can be 64-bit.
