Final answer:
Syntax is the set of conditions that define how instructions are written for machines, particularly in programming. It encompasses the rules used to combine words and symbols in code. Option 4 is correct.
Step-by-step explanation:
The set of conditions in which instructions for machines, such as computers, are written is known as syntax. Syntax is the manner by which words are organized into sentences or commands that a computer can understand.
In programming, syntax refers to the rules and structures used to combine symbols, characters, and keywords to construct lines of code that perform specific tasks when executed by a machine. Languages such as Python and Modula-3, possess their unique syntax, which programmers must follow to write correct and functional program code.
During the process of coding, trial and error is a common problem-solving strategy where multiple iterations may take place before achieving the correct syntax or result. Recognizing whether a problem is set up incorrectly or correctly will depend on understanding the particular syntax rules of the programming language you are using, as well as the objectives you are trying to achieve, such as word processing or solving an equation.
