C language is machine dependent

Answer 1

Yes c is a complete machine dependent language as the memory allocated to its various variables having various data types is different.

For example in some compilers the memory allocated to the char data type is 1 byte but in many compilers it may be 2 bytes also>>>

thanks

Answer 2

Some are dependent and some are platform independent.

Machine language is generally machine dependent, as it varies from process to processor. Processor models within the same family can share a common pool of machine language instructions, which could be seen as a limited form of machine independence.

However, virtual machine language such as those used in the .NET or Java platforms are designed to be subject to runtime interpretation and runtime "just-in-time" compilation. These languages are designed for machine independence, as they do not generally depend a specific processor hardware.
