Does the size of an int depend on the compiler and/or processor?

Question

Would the size of an integer depend upon the compiler, OS and processor?

Answer 1

size of data type basically depends upon the type of compiler and compilers are designed on the basis of architecture of processors so externally data type can be considered to be compiler dependent.for ex size of integer is 2 byte in 16 bit tc compiler but 4 byte in gcc compiler although they are executed in same processor
