Programming in C is a tremendous asset in those areas where you may want to use assembly language, but would rather keep it a simple to write and easy to maintain program. C does have a few surprises Many High level languages, like PASCAL, are highly disciplined and structured. C is much more flexible and free-wheeling. This freedom gives C much more power that experienced users can employ.

Characteristics of C: We briefly list some of C's characteristics that define the language and also have lead to its popularity as a programming language.

• Small size

• Extensive use of function calls

• Loose typing -- unlike PASCAL

• Structured language

• Low level (Bitwise) programming readily available

• Pointer implementation - extensive use of pointers for memory, array, structures and functions.

C has now become a widely used professional language for various reasons.

• It has high-level constructs.

• It can handle low-level activities.

• It produces efficient programs.

• It can be compiled on a variety of computers.

Note: There is no Boolean type in C - you should use char, int or (better) unsigned char. You can declare the const before or after the type. Choose one an stick to it. It is usual to initialize a const with a value as it cannot get a value any other way. The preprocessor # define is another more flexible method to define constants in a program. You frequently see const declaration in function parameters. This says simply that the function is not going to change the value of the parameter.
