A High Level Language (HLL) is a Computer Programming Language that supports system development at a high Level of Abstraction. With the development of programs in high level languages programmers are freeing from keeping in his mind lots of details that are irrelevant to the problem at hand. High level language is not limited by the computers; it is designed for a specific job and it’s easier to understand. HLL is more like human language and less like machine language. The first high-level languages were introduced in the 1950’s.

Examples of High-level Programming Language:

There are many high-level languages in use, including: BASIC, FORTRAN, C, C++, COBOL, Java, Pascal, Perl, PHP, Python, Ruby and Visual Basic.

Benefits of higher-level language:

Since last two eras High-level languages are preferred by the programmers because HLL provide a convenient abstraction of the underlying system suitable for problem solving. The benefits of programming in a high-level language rather than in an assembly language or low level language include the following:

Readability: High Level Language supports a high level of abstraction for both operations and data. This functionality enhances the workability of the program to read and modification.

Machine independent (portable): High-level language provides higher portability for a program because HLL contain very few machine-specific details, and HLL written code can be used with little or no modification on different computer architecture. As long as there is a translator for the language on particular computer architecture, the program can be used on that architecture.

Data representation is hidden: High-level language provides software data maintainability feature, which involves activities ranging from fixing bugs to generating the next version of the software. It is well maintain as per security and flexible to understand the future enhancement of a particular software program.

Easy error-checking: Programs written in a high-level language are easier to understand and, when good programming practices are followed, easier to maintain and checking programming code error.

Faster program development: Many high-level languages provide structures (sequential, selection, iterative) that facilitate program development. Programs written in a high-level language are relatively small and easier to code and debug.
