In simple words, a programming language is a set of instructions written in a specific language (such as C, C++, Java, or Python) that tells a computer what to do to perform a specific task. It is like a set of commands that a programmer uses to communicate with a computer. Programming languages are used to write computer programs and software. They are like a mode of communication between humans and computers. A programming language has a unique set of keywords and a special syntax for organizing program instructions. Some programming languages use real words for some of the commands, making the language easier for humans to understand. There are many programming languages, and each has its own unique features and uses.
