Platform dependent language like C, C++?

[sanketbarot]

Why are C, C++ called platform dependent languages ? what does it mean?

[tyreld]

C and C++ are not per say platform dependent. There are several standards for the basic language features of C and C++. These basic language features in theory should be supported on any platform that has a standard compliant compiler. It is the use of libraries bound to a particular platform that make a C or C++ program platform dependent..

It is the use of libraries bound to a particular platform that make a C or C++ program platform dependent..

Or the programmer making assumptions that cause the code to be platform specific, for instance assuming that the platform is big or little endian will necessarily reduce the code to only working on platforms displaying that property.
