C was developed by Dennis Ritchie between the year 1969 and 1973 at AT&T Bell Labs.

C++ was developed by Bjarne Stroustrup in 1979.

C does not support polymorphism, encapsulation, and inheritance which means that C does not support object-oriented programming.

C++ supports polymorphism, encapsulation, and inheritance because it is an object-oriented programming language.

C is a subset of C++.

C++ is a superset of C.

C contains 32 keywords.

C++ contains 52 keywords.

For the development of code, C supports procedural programming.

C++ is known as a hybrid language because C++ supports both procedural and object-oriented programming paradigms.

Data and functions are separated in C because it is a procedural programming language.

Data and functions are encapsulated together in form of an object in C++.

C does not support information hiding.

Data is hidden by Encapsulation to ensure that data structures and operators are used as intended.

Built-in data types are supported in C.

Built-in & user-defined data types are supported in C++.

C is a function-driven language because C is a procedural programming language.

C++ is an object-driven language because it is object-oriented programming.

Function and operator overloading is not supported in C.

Function and operator overloading is supported by C++.

C is a function-driven language.

C++ is an object-driven language

Functions in C are not defined inside structures.

Functions can be used inside a structure in C++.

Namespace features are not present inside the C.

Namespace is used by C++, which avoids name collisions.

Header file used by C is stdio.h.

Header file used by C++ is iostream.h.

Reference variables are not supported by C.

Reference variables are supported by C++.

Virtual and friend functions are not supported by C.

Virtual and friend functions are supported by C++.

C does not support inheritance.

C++ supports inheritance.

Instead of focusing on data, C focuses on method or process.

C++ focuses on data instead of focusing on method or procedure.

C provides malloc() and calloc() functions for dynamic memory allocation, and free() for memory de-allocation.

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

Direct support for exception handling is not supported by C.

Exception handling is supported by C++.

scanf() and printf() functions are used for input/output in C.

cin and cout are used for input/output in C++.
