Difficult programming challenge
Please support our C++ advertiser: Intel Parallel Studio Home
Thread Solved |
I have a very hard programming challenge and i need help... I have nothing so far, so im hoping somebody could help me build it...
Im to write a program that uses a structure to store student name, student ID number, pointer to and array of test scores, average test score, and course grade.
Program should keep list of tests scores for a group of students, ask the user for how many test scores and how many students there are. It should then dynamically allocate (pointer?) and array of structures. Each structure's test menber should point to a dynamically allocated array (pointer?) which will hold the tests scores.
After this, program should ask for ID number and test scores for each student. Average test score should be calculates and stored in the average member of each structure. score grade should be computed (91-100=A and so on).
Score grade should then be stored in the Grade member of each structure...once data is calbulated, a table should show student's name, ID number, average test score, and course grade...
These are the instructions, from what I understand, I think it should look like this...
ask for students...
ask for test scores..
build arrays
student 1: ID? name?
test1:
test2:
student2: ID?Name?
test1:
test2:
something like that...help!!!

That looks suspiciously like a homework question. Perhaps you should give a shot at coding it a bit yourself before we give you a hand.

PMs asking for help will not be answered, post on the forums. That's what they're there for.

Poor me ! it's an online class, it was the only option and the teacher sucks. We have a tutor that's a fellow student and he couldn't even help me do this one . So please help with whatever hints you can give me Here's what I have:
#include <iostream>
using namespace std;
const int NAME_LENGTH= 80;
const int SIZE;
struct studentData
{
char studentName[NAME_LENGTH];
int Idnum;
int numTests;
int *testsPtr;
double Average;
char Grade[SIZE];
};
int main()
{
cout<<"How many test scores are there?"<<endl;
cin>> numTests;
cout<< "How many students are there?"<<endl;
cin<< numStudents;
studentData *students;
students = new student[numStudents];
for (int count=0; count<numStudents;count++)
{
cout<<"Enter the Test scores for student number "<<(count+1)<<endl;
for (int count=0; count<Tests; count++)
{
cout<< "Enter test score #"<<(count+1)<<": "endl;
cin>> Tests[count] Okay I guess my first question is how do I dynamically allocate an array of structures correctly and how do I get each structure's tests to point to a dynamically allocated array that hold these test scores?
I have no idea hat to do from here on Please help:

Is this the total number of test scores for ALL students combined or for EACH student?
And does each student have the same number of test scores or does it vary from student to student? Also, what does SIZE represent here?
