Final answer:
The statement that all programs must end with a 'Stop' command is false. Modern programming languages typically end a program when the main function completes or the final line executes, without a specific 'Stop' command.
Step-by-step explanation:
The statement that 'all programs must end with a 'Stop' command is false. In modern programming languages, the end of a program is typically signified when the main function (often called main in languages like C and C++) reaches its closing brace, or when the script executes its final line, as in interpreted languages like Python or JavaScript. Programs can also end by reaching a return statement, exiting with an exit function call, or through other program control structures.
As an example in Python, which is widely taught in high school:
def main():
print("Hello, World!")
main()
When the main() function is called and completes execution, the program will naturally terminate. There is no need for any explicit 'Stop' command. However, in certain older programming environments or languages, especially those related to batch processing or command line interfaces, a 'Stop' command or equivalent might have been used. This practice is not common with modern application development.
