Question

Write a void function definition for a function called zero_both that has two reference parameters, both of which are variables of type \(i n t,\) and sets the values of both variables to \(\theta\)

Short answer

Answer: The "zero_both" function is a void function that takes two reference parameters of type int and sets their values to zero. The reference parameters are defined using the '&' symbol after the data type, such as int &a and int &b. Inside the function body, the reference parameters are used like regular variables to set their values to zero.

Step-by-step solution

Define a function with reference parameters

To define a function with reference parameters, we use the '&' symbol after the data type. In this case, the data type is 'int'. We have two reference parameters: int &a and int &b.

Set the values of both variables to zero

Inside the function body, you can use the reference parameters 'a' and 'b' as you would use any other variable. Simply set them to zero.

Write the void function definition for zero_both

Here is the complete function definition: ```cpp void zero_both(int &a, int &b) { a = 0; b = 0; } ``` This function, when called with two int variables as arguments, will set their values to zero.
