Advantages of High-Level Languages 1. Easy to Learn The high-level languages are very easy to learn than low-level languages . The statements written for the program are similar to English like statements. 2. Easy to Understand The program written is high-level language by one programmer can easily be understood by another because the program instructions are similar to the English language? 3. Easy to Write Program In high-level language, a new program can easily be written in a very short time. The larger and complicated softwar e can be developed in few days or months. 4. Easy to Detect & Remove Errors The errors in a program can be easily detected and removed. Mostly the errors are occurred during the compilation of new program. 5. Built-in Library Functions Each high-level language provides a large number of built-in functions or procedures that can be used to perform specific tasks during designing of news programs . In this way, a large amount of time of programmer is saved. 6. Machine Independen ce Program writte n in high-level language is machine independ ent. It means that a program written on one type of computer can be executed on another type of computer. o In high level languages we can write programs in English like manner and is more convenient to use. Programmer can perform complex task by using high level languages with less efforts. There are different high level languages such as FORTRAN (Formula Instructions), BASIC (Beginners All Purpose Symbolic Instruction Code), COCOL (Common Business Oriented Language), PASCAL, C++, Visual Basic, VB. Net etc. High level languages have many advantages. High level la nguages are very similar to nature language such as English so they are very easy to learn and use. For higher level languages programmers need s not to learn about internal structure of the computer. High level language programs require less time and efforts that due the preparation cost of the program. High level programs are very easy to maintain than lower level languages. In lower level languages instruc tion are difficult and very hard to locate, correct and modify but in high level languages it is very easy to understand and modify when desired. In high level languages programmer needs not to write all steps because computer take cares of all small error. Compilers of high level languages automatically catch and point out the errors made by the programmers.
