Consider the following code snippet:#include <iostream>void swap...
Explanation:

swapValues Function:
- The swapValues function takes two integer references as parameters and swaps their values.
- It stores the value of 'a' in a temporary variable, then assigns the value of 'b' to 'a', and finally assigns the value of the temporary variable to 'b'.

Main Function:
- In the main function, two integer variables x and y are initialized with values 5 and 10 respectively.
- The swapValues function is called with x and y as arguments.
- After the function call, the values of x and y are swapped.

Output:
- After the swapValues function is called, the values of x and y are swapped.
- Therefore, the output of the code will be "10 5".

Consider the following code snippet:#include <iostream>void swap...
The 'swapValues' function swaps the values of the variables 'a' and 'b'. In the 'main' function, 'x' and 'y' are passed as references to 'swapValues', which swaps their values. Therefore, the output will be 10 5.
