Concept explainers
a)
Pass-by-value:
A copy of the argument’s value which is passed into the parameter variable is referred as pass by value. In the pass by value, the called method creates new variables to store the value of the arguments passed to it. The changes made in the formal parameters do not reflect on the actual parameters.
Example:
changeVal(int num);
Here, “changeVal” is the method name and the “num” is the argument passed by value.
b)
Pass-by-value:
A copy of the argument’s value which is passed into the parameter variable is referred as pass by value. In the pass by value, the called method creates new variables to store the value of the arguments passed to it. The changes made in the formal parameters do not reflect on the actual parameters.
Example:
changeVal(int num);
Here, “changeVal” is the method name and the “num” is the argument passed by value.

In the student sample programs for this book, you will find a text file named 8_ball_responses.txt. The file contains 12 responses, such as “I don’t think so”, “Yes, of course!”, “I’m not sure”, and so forth. The program should read the responses from the file into a list. It should prompt the user to ask a question, then display one of the responses, randomly selected from the list. The program should repeat until the user is ready to quit. Contents of 8_ball_responses.txt: Yes, of course! Without a doubt, yes. You can count on it. For sure! Ask me later. I'm not sure. I can't tell you right now. I'll tell you after my nap. No way! I don't think so. Without a doubt, no. The answer is clearly NO. (You can access the Computer Science Portal at www.pearsonhighered.com/gaddis.)arrow_forward
