Final answer:
The truth value of the statement that 'You must furnish an argument with a function call' depends on the function's definition. With functions that require parameters, the statement is true, while for parameter-less functions, it is false.
Step-by-step explanation:
The statement 'You must furnish an argument with a function call' can be true or false depending on the context of the function being called. In programming, if a function is defined to accept parameters, then it is indeed true that an argument must be provided when the function is called. However, if a function is defined to take no parameters, then no arguments need to be furnished with the function call, making the statement false.
It is essential to understand the function definition to determine whether this statement is true or false. For example, consider a function add(int a, int b) that requires two arguments, a and b. In this instance, it is true that arguments must be furnished with the function call, such as add(5, 10). Conversely, if the function is defined like greet() with no parameters, then the call greet() does not need any arguments, which would make the statement false.
