Lab 9-6: Pass by Reference and Pass by In this lab, you complete a partially written C++ program that includes a function named multiplyNumbers () that multiplies two int values to find their product. Three ints should passed to the multiplyNumbers() function, the two numbers to be multiplied (numl and numa should be passed by value, and another int (product) to hold the product of the two number should be passed by reference, enabling the multiplyNumbers () function to change its value The source code file provided for this lab includes the necessary variable declarations and input and output statements. Comments are included in the file to help you write the remainder of the program. 1. Open the source code file named MultiplyTwo.cpp using Notepad or the text editor of your choice. 2. Write the multiplyNumbers () function, the function declaration, and the function call as indicated by the comments. Save this source code file in a directory of your choice, and then make that directory your working directory. 3. 4. Compile the source code file MultiplyTwo.cpp. 5. Execute the program. Rewrite the mu ltiplyNumbers () function to pass the two numnbers (num1 and num2) b- value and to pass product by address. 7. Save this program as MultiplyTwo2.cpp. 8. Compile MultiplyTwo2.cpp. 9. Execute the program. Both programs (MultiplyTwo.cpp and MultiplyTwo2.cpp) should generate the same output.
