Question

Which of the following are TRUE? A function can call another function. As long as the function is defined anywhere in your program, it can be used anywhere else. A function definition can contain another function definition. If you have function prototypes, the order in which you define your functions is important.

Answer 1

Option 1: A function can call another function.

Step-by-step explanation:

• A function can call another second function by mentioning it in the definition. So the first option is true.
• A function must be defined before calling it. Moreover it can only be used inside the main body.
• A function definition can may call another function by naming it but cannot have the definition of the second function inside it.
• The order of defining functions is not important because the only thing matters is that they should be defined before they are called never depending on the order of definition.
