The function
pow uses pass by value to call the function.Solución
In the function declaration
double pow(double base, double exp), the mechanism used to call this function is known as pass by value.Explanation:
-
Pass by Value: This means that when the function is called, the values of the arguments are copied into the function’s parameters. Any changes made to the parameters inside the function do not affect the original arguments.
-
Pass by Name: This is a mechanism where the actual parameter is substituted for the formal parameter in the function body. This is not commonly used in most programming languages.
-
Call by Value by Name: This is not a standard term and is not applicable in this context.
In summary, since the parameters
base and exp in the function pow are passed by value, the correct answer is pass by value.Respondido por UpStudy AI y revisado por un tutor profesional

In the function declaration
double pow(double base, double exp), the mechanism used to call this function is known as pass by value. In this context, it means that when you call the function, a copy of the actual parameters is passed to the function. This ensures that any modifications made to the parameters inside the function do not affect the original variables used in the function call.When using pass by value, it is essential to remember that the function operates on copies of the arguments. Therefore, if you need to maintain changes outside of the function, you’ll either have to return values or use pass by reference to manipulate the original variables directly.
