C is a subset of C++.

Since C is a procedural programming language, data and functions are separate entities.

C is a function-driven language.

C does not support function and operator overloading.

C does not have the namespace feature.

C uses the scanf function and the printf function for input and output.

C uses the malloc()/calloc() functions for dynamic memory allocation, and the free() function for memory de-allocation.

C++ is a superset of C.

In C++, data and objects are encapsulated together in the form of an object.

C++ is an object-driven language.

C++ supports function and operator overloading.

C++ uses namespace which prevents name collisions.

C++ uses the cin and cout objects for input/output.

C++ uses the new operator for memory allocation and the delete operator for memory de-allocation.
