CSCI 159 Quiz 4

Name:

The quiz is open notes, open book, and you are permitted to use your linux accounts to write/check practice code if desired. For example, you could use the following to edit, compile, and check code in a quest1.cpp file:

    gedit quest1.cpp &
    g++ quest1.cpp -o quest1x
    ./quest1x

There are two questions and you have 60 minutes to complete the quiz.
The quiz must be completed as a completely individual exercise: you cannot request or accept help from any other source (human or ai) other than the course instructor, and you cannot give help to anyone else for the quiz.
If you finish early you can leave or stay and work quietly while others finish their quizzes.

Question 1: structs and arrays

Suppose we have the following struct, used to keep track of the amount of cash someone has:

   struct CashCarried {
      string name;  // name of person carrying the cash
      float  cash;  // amount of cash they're carrying
   };

Complete the sumCash function below that takes an array of CashCarried structs and computes and returns the total cash carried by everyone listed in the array (add up all the cash fields and return the result). The N parameter specifies how many entries there are in the array.

float sumCash(CashCarried people[], int N)

Question 2: checking a struct

Based on the same CashCarried struct as in question 1, the checkEntry function below checks the validity of a struct and returns true if it is valid, false otherwise.

The rules for validity are:
(i) the length of the name must be at least 3 characters (checkable with .length())
(ii) the cash amount cannot be negative.

Complete the checkEntry function.

bool checkEntry(CashCarried entry)
