Overview The C language was originally designed from 1969 to 1972, by Dennis Ritchie to program the Unix operating system. C Features A C program is a set of functions that return or not a value, and global variables. Functions and variables have prototypes in header files for external use. The programmer must manage itself the memory, using pointers and functions to allocate of free fields of memory. By declaring instances of classes you can reuses set of variables and methods without to define them again.
Memory management is unchanged.
Overloading allows to declare a method with different parameters. Classes inherits one from other and share their methods. C has known success thanks to the liberty if offers to programmers. The drawback is the difficulty to debug the programs. It is fast, and a large collection of APIs is available.
