The purpose of a comment is to help the compiler understand your program and a comment provides information to the programmer.
What is a comment and its use ?Comments are text notes that are added to the program to provide explanations for the source code. They are used in a programming language to document the program and remind programmers of the tough things they just accomplished with the code. They also aid in the understanding and maintenance of code for future generations. These are considered non-executable statements by the compiler. Each programming language has its own method for incorporating comments in the source code. We can write the pseudocode that we planned before writing the original code in the comments. Pseudocode is a language that combines conversational language and high-level programming. This makes it easier to review the source code because pseudocode is more understandable than the program. The programmer uses code descriptions to help others comprehend his or her intent. It contains the code's summary. The process is explained in the comments. Diagrams and rigorous mathematical proofs are examples of such explanations. This could be interpreted as an explanation of the code rather than a clarification of its intent. For example, a programmer may provide a comment explaining why an insertion sort was chosen over a quicksort, as the former is, in theory, slower.What is a compiler ?A compiler is a computer program that converts computer code written in one program into another.
