Hello there everyone before I post my ( probably not elegant) code I Would like to first give the community an idea of what I am doing. I am writing a grade organizer program to where I can store a test, lab, or homework grade respectively. I have finished the portion of this project where I can input the data and have even displayed it during the input to make sure that the data was being stored into the structure properly. I need some help with a few things here, first things first I need help with linked lists, quite frankly i'm a year's worth out of practice in C++ and would like some assistance maybe turning these structures into functional linked lists. The second question I am asking is how would I write this to a file assuming I actually wanted to make this program a usable Executable without a compiler handy. In otherwords it would be nice if I Could store the nodes in the linked list and be able to open and save them when needed. I apologize if I'm a little vague here, I have done some snooping online and have found little help, even if you guys had a few helpful links to what I am looking for that would be most helpful.
Now without further hesitation, THE CODE:
#include <iostream>
#include <string>
using namespace std;
struct T_storenode{ // Structure to create a record of a tests name,score,and weight in final grade;
char name[30];
char date[30];
float score;
struct node *next;
}T_value[250]; // array for the structure.
struct L_storenode{
float score;
char name[30];
char date[30];
struct node *next;
}L_value[250];
struct H_storenode{
char name[30];
char date[30];
float score;
struct node *next;
}H_value[250];
int OptionMenu(int); // menu proto
void GradeAve(float GA_number, float G_ave,float GA_sum, int GA_count); // case 1 proto
void Tests_store(T_storenode test); // case 2 proto
void Lab_store(L_storenode test);
void HW_store(H_storenode test);
int main()
{ float GA_sum=0; // sum for case 1
float GA_ave=0; // average for case 1
int menunumber=0; // menu selection
int GA_count=0;
float GA_number=0;
int menu_number_returned=0; // menu value returned for switch statement.
int T_count = 0;
menu_number_returned = OptionMenu(menunumber);
// call function to menu select and return value to menu_number_returned
system("cls"); // clear screen
switch(menu_number_returned) // Switch statement to process the menu selection screen
{
case 1:
GradeAve(GA_number,GA_sum,GA_ave,GA_count); // menu selection 1 call; find average of a test score
break;
case 2:
Tests_store(T_value[250]); // menu selection 2 call; still working on this...
break;
case 3:
Lab_store(L_value[250]);
break;
case 4:
HW_store(H_value[250]);
break;
//case 5:
//break;
//case 6:
//break;
//case 7:
//break;
default:

}Thanks in advance to anyone who took the time to read/help me with this! Thank you. Also I was wondering if you guys would be able to tell me at what level you think my program skills are for what I've written, obviously not the best but I'm hoping the community see's potential in me as a future programmer as I would love to do this for a living. Thanks everyone!
