Programming languages are the main tools a computer scientist uses to work with computers. Only a few decades ago, in the beginning of computer programming, so-called first generation languages were used to make computers solve problems. Such languages are operating on the binary machine code level, which is a sequence of 0s and 1s that instruct the computer to perform actions. Thus programming was very difficult and troublesome. A small step forward was done by the introduction of programming in octal or hexadecimal code.
