Welcome to class!

In today’s class, we will be talking about the programming language. Enjoy the class!

Programming Language

This is a process that results in the development of a set of detailed instructions following a pattern of a particular programming language necessary to solve a problem. A programming language is a formal constructed language designed to communicate instructions to a machine, particularly a computer. Programming languages can be used to create programs to control the behaviour of a machine or to express algorithms.

A vocabulary and set of grammatical rules for instructing a computer to perform specific tasks. High-level programming languages, while simple compared to human languages, are more complex than the languages the computer understands, called machine languages. Each different type of CPU has its unique machine language.

Levels of languages

Each language has a unique set of keywords (words that it understands) and a special syntax for organizing program instructions.

1. Machine language
2. Low-level language
3. High-level language
4. Natural level language

Machine language:

This was the first level of language known to man. It involves the use of binary digits i.e. 0s and 1s to write programs and instructions.

Low-level language:

This was the next language developed after the machine language. It involves the use of binary code.

High-level language:

They are highly developed languages and are currently used by programmers in the world today. It involves the use of English to write programming instructions. The invention of high-level language has made it easy for programmers to develop programs in the shortest possible time.

Types of high-level programs

• BASIC
• FORTRAN
• COBOL
• PASCAL
• C – Language (C++)
• JAVA

Natural language: This involves different types of languages known to mankind e.g. Igbo, Yoruba, Hausa, Chinese, Ghanaian languages.
