C++ is an improvement over C. C and C++ use a completely different approach. The main focus in C is on procedures(functions) whereas in C++ basically Classes and Objects are used. Due to increasing need of data security, a data hiding feature was also added to C++ by using access specifiers. C supports user defined data types i.e. struct, but it was unable to support functions. The classes in C++ support this feature. Some of the main differences between C and C++ are:
