What punctuation mark does most commands in C programming end with?

In C programming, most commands and statements conclude with a semi-colon. This punctuation mark serves as a statement terminator, indicating to the compiler that a complete instruction has been provided. By using the semi-colon, programmers can clearly demarcate individual instructions, which is essential for proper parsing of the code by the compiler. This helps prevent confusion and ensures that each command is processed as intended.

The requirement for a semi-colon is foundational in C programming, as it establishes the end of declarations, expressions, and other statements. Omitting the semi-colon can lead to syntax errors, making it crucial for beginners to remember this convention when writing their code.
