Characteristics of High Level Languages

• Characteristic of High Level Language:-

                     High level languages have several advantages over Low Level Programming Languages.

• Easy to learn:-

 

                    The high Level Languages are close to human languages. The instructions written in high level languages are similar to English like words and Statements. This makes the high level languages easy to learn and use.

• Easy to detect errors:-

                    The logic of the program written in high level languages is very simple and easy. The instructions of program are like English language statements. In case of errors, it is very easy to detect (or find) and remove errors in the Program. It is also easy to modify the Program.

• Machine Independent:-

                    The program written in High Level Language is machine independent. It means that a program written or compiled on one type of Computer can be executed (run) on another different type of Computer that has different architecture.

• For Example:-

                    A program written on a Computer using Intel Processor can be run on computer having Motorola Processor (but with a little Modification).

• Availability of Liberty Functions:-

                   Every High Level Language provides a large number of Built in functions (or library functions) that can be used to perform specific tasks during designing of new Programs.

• For Example:

                  To computer the square root of a number, the programmer can use the available built in function without writing its own code. This way of writing a program reduces the development time of a program. This software is developed in a very short time.

• Shorter Program:-

                         The Program written in high level language is shorter than the program written in low level language. A single instruction of the program written in High Level Language may be equivalent to many instructions of low level programming language.

• Well defined Syntax and standard:-

                         Every high level language has a standard syntax. The standard is approved (or established) by international organization. The most popular organization is ANSI (American National Standard Institute). The translator programs are written according to the standard syntax of the language. Therefore, high level languages describe a well defined way of writing programs.

• Source code is understandable by another programmer:-

                         The instructions of the program written in high level language are like English language statements. These are written according to the standard syntax of the language. Therefore, a computer programmer can easily understand a program written by another programmer.
