Question

Look at the following function prototype.

int myFunction(double, double, double);

How many parameter variables does this function have?
A) 1
B) 2
C) 3
D) Can't tell from the prototype

Answer 1

The function 'myFunction' has 3 parameter variables, all of which are of type double.

Step-by-step explanation:

The function 'myFunction' is declared with the prototype int myFunction(double, double, double);, indicating that it accepts three parameters, all of type double. In programming, these parameters act as variables within the function, allowing it to receive and process specific values during execution. The three parameters are separated by commas within the parentheses. For example, when calling myFunction(x, y, z), the function can access the double values assigned to x, y, and z. This design enables flexibility and reusability, as different values can be passed to the function depending on the context, making it a versatile tool in mathematical or computational tasks.
