2. Consider the following statements:

Question

struct dateStruct

{

     int day; // assume 1 <= day <= 31;

     int month; // assume 1 <= month <= 12;        

     int year; // assume 0 <= year <= 2100;

};

struct student

{

    string name;

    dateStruct dob;

    int grades[5];

};

 

dateStruct today;

student s;

double average;

(a) Write a statement that makes today’s month represent February. (b) Write a statement that makes s’s name be Natalie Portman.

(c) Write a statement that makes s’s birth date the same as today’s.

(d) Write a statement that prints the month s was born.

(e) Write a segment of code that assigns average the average of s’s five test grades.

Answer 1

1. Make today's month represent February

Make a variable s of type struct dob.  Set the month member to be 2.  I recommend using a #define FEBRUARY 2, as "magic numbers" are not good program practice. structure and class members are accessed using the '.' operator.

 

2. Write a statement that makes s's name be Natalie Portman

A. Similar to the previous problem; create a struct variable s of type student and set s.name

 

3. & 4. are similar assignment statements.

 

5. This can be done with simple for loop to walk through the student member element, grades. Have a new variable (I suggest using float, as you'll be calculating average) to sum up the values.
