Which command would you use to end a statement in C?

In C programming, a statement typically ends with a semicolon. This punctuation mark is crucial because it tells the compiler that the statement is complete and allows it to parse the code correctly. Each statement, whether it’s a variable declaration, an assignment, or a control structure, requires a semicolon to indicate its termination.

Using a period, colon, or comma would not satisfy the syntax rules of C language. Specifically, a period is often used in languages like Python for method calls but does not serve the same purpose in C. A colon is used mainly in specific constructs such as labels, but not for ending regular statements. A comma is used to separate elements within a statement, such as in function arguments, but again does not signify the end of a statement. Thus, the semicolon is the necessary punctuation in C to denote the conclusion of each separate instruction, ensuring the code executes as intended.
