C++ Project, need all the help i can get!

are you allowed to write your own header files for class definitions? or are you just working with an array of like structs or something where the struct would be:

struct LightingMode
{
char option;
int floodlightCount;
char givenOrRandom;
double floodlightDistance[floodlightCount]; //its been awhile since i worked with arrays that aren't in a class without a constructor, not sure if syntax is legal
int/double floodlightPower;
double floodlightHeight[floodlightCount];
}

//calculation functions goes here

as for putting the values in the array, after calculating the value of light in a 2d cell, store the value in that arrays cell using a double for loop. for example

double courtCells[cellHeight][cellWidth];
LightingMode first;

for(int i = 0; i < cellHeight; i++)
{
for(int j = 0; j < cellWidth; j++)
{
courtCells[i][j] = Function1(First ,Function2(first));
}
}

where function 1 is the light level(that returns a double) whose parameter is a LightMode struct and an int value(distance), which is calculated by passing the LightMode struct into Funtion2(the distance calculating function whose parameter is a struct and returns an int)

at least i think, not sure how far in your class youve gotten into in C++

using a while(fin.good()) loop or similar loop, I would input the data into the struct directly with fin(or whatever you decide to name it to the point where you get to

fin >> givenOrRandom;
where there's one if/else statement where it checks the char where its either given or random. so you must do one or the other
if(givenOrRandom == C) do something
else do the other thing

I would personally have done this in a class header file(given my current knowlege, as a constructor could easily just do all the work for you)
