Fundamental Differences Between C and C++

Some of the new language features that C++ provides over C have nothing directly to do with OOP. The following sections preview some of the non-OOP language differences that you'll find between C and C++.

Comments

One of the differences is the way that C++ allows you to place comments in your C++ programs. (A comment in C or C++ is the same as a remark in Visual Basic.) Any text that follows a double slash, //, is considered by C++ to be a comment. Therefore, you don't need a closing comment symbol, such as */, as you need in C. The following shows the same comment in C++ and then in C:

intCust++;  // Add to customer count

intCust++;  /* Add to customer count */
