What symbol is used to indicate the start of a procedure in Karel?

In Karel programming, the symbol used to indicate the start of a procedure is a vital part of structuring the code for better organization and clarity. The correct identification of this symbol helps to signal the beginning of a defined procedure, which encapsulates a series of instructions that Karel will execute when the procedure is called.

In Karel's syntax, the term "function" is used to denote the beginning of such procedures. It serves to create reusable blocks of code that can be executed multiple times throughout a program. The use of "function" helps in making the program more modular and manageable, as each function can perform a specific task, reducing redundancy and simplifying debugging.

Understanding this concept is crucial for writing effective Karel programs and allows programmers to enhance code reusability and organization. Thus, recognizing "function" as the correct term is essential for anyone learning Karel programming.
