CSCI 160 practice questions

Practice programming question: structs

What is the output from the following program?

#include <cstdio>
#include <cstring>

const int Len = 80;
struct Names {
   char given[Len];
   char family[Len];
};

void EditNames(Names &n);
Names GiveNames();

int main()
{
   Names N = { "try", "this" };
   printf("%s,%s\n", N.given, N.family);
   strcpy(N.given, "me");
   strcpy(N.family, "too)";
   printf("%s,%s\n", N.given, N.family);
   EditNames(N);
   printf("%s,%s\n", N.given, N.family);
}

void EditNames(Names &n)
{
  strcpy(n.given, "changed)";
  strcpy(n.family, "both");
}

Write the definition for an AssignmentMark struct with the following fields:
- a string for the name of the assignment (e.g. "Pex1")
- an int for the maximum possible mark for the assignment,
- a float for the actual mark received for the assignment,
- a float for the value of the assignment as a percent of the total course mark (e.g. 15.0 if the assignment is worth 15% of the total grade).
Write the definition for a StudentMarks struct with the following fields:
- a long for a student number,
- a string for the student's linux login id,
- a string for the student's family name,
- a string for the student's given name,
- an array of AssignmentMark structs (from the previous question), where the size of the array is given by the constant NumAssignments
- a float for the student's final mark (as a percent),
- a string for the student's final letter grade.
Write a function, PrintMark, that takes a StudentMarks struct as a parameter and prints the fields
Write a function, PrintCourseMarks, that takes an array of StudentMarks structs as one parameter, and the number of students in the course as a second parameter, and calls PrintMark once on each student's data.
