6. Write a note to develop a habit of writing a comment. Especially the procedures or variables that others are difficult to understand must be annotated. After a month, maybe you also need to see the comment.
INT x = 100;
INT Y = 1000;
IF (x A = 0; Else a = 1; What do you know what the above program means? If you don't know what the variables x, y, and a refer to what is, it is difficult to understand. Let us give it a marked comment again: / * * Programs detection profit or loss * / INT x = 100; / * X is the total amount of the sale * / INT Y = 1000 / * Y is the cost of doing books * / Int a; / * Confirm that there is a profit * / / * Comparison X and Y: * / IF (x / * 1 means losses * / a = 1; Else / * 0 Refers to the profit * / A = 0; This note, people who don't understand C language will also understand what the statements mean, what each variable refers to. Write a comment is a good habit, but don't comment. The comment is for a so-understanding, not for writing a long-editing article. INT profit = 1; / * Profit equal to 1 ?? * / INT LOSS = 0; / * Loss is equal to 0 ?? * / / * If the profit is equal to 1 * / IF (Profit == 1) / * Print "win profit" ?? * / Printf ("We Made a Profit! / N"); /* if not */ Else / * Print "We lose" * / Printf ("We Made a Loss! / N"); This comment is a waste of time. Generally, a quarry is required, and the comment is required, and the purpose of the program, the use of a function, Procedule, etc. also needs.
