To let the computer process a task it's necessary to enter instructions sequence. This instructions sequence is commonly called as an algorithm. The sequence of instructions expressed in programming language is called program. In current computers heart of all the calculations is the processor. It processes the instructions in assembly language. The construction of advances algorithms in assembler is quite difficult. The reason is principle of the processor construction. The processor can work only in binary number system and can process only several basic operations. Instructions in assembler consists only from the operation and binary representation of the value stored in the computer memory. There is a semantic gap between the assembler language and human thinking. The gap can be crossed by programming languages introduction. There is a vast amount of programming language dialects and it differs in the complexity. The complexity of programming language is the bigger the closer is to the human cognition. The meaning of higher programming languages is to offer the most understandable and most powerful programming environment. The higher programming languages achieve that by more complex construct implementation and different abstraction of the data structures. The way that enables computer to understand the higher languages is the existence of so-called compiler. Compiler translates program from the programming language to the assembler language. |=--------------------------------------------------=| ; v | Thanks Linux and Vim | buy me a coffee | o |; |=--------------------------------------------------=| |
