Comparison: C++ is an extension to the C language. When C++ is used as a procedural language, there are only minor syntactical differences between them.
Contrast: When used as a procedural language, C++ is a better C because:
It vigorously enforces data typing conventions.
It allows variables to be defined where they are used.
It allows the definition of real (semantically significant) constants.
It allows for automatic pointer dereferencing.
It supports call-by-reference in addition to call-by-value in functions.
It supports tentative variable declarations (when the type and location of a variable cannot be known before hand.
