Hello,
I'm currently doing my end of semester assignment where I have to code a robot to navigate a grid checking the squares to see if there's an object in them.
Anyway on one part of the assignment I need to store my data in a struct.
PDF of that Task: http://users.aber.ac.uk/owj3/PDF/map.pdf
I've declared the struct before the setup(); like this:
struct GridSquare{
int xpos; // current X axis position in grid
int ypos; // current Y axis position in grid
boolean checked; // Whether the square has been checked or not
boolean occupied; // Whether an object was detected or not
and then when the robot checks the squares it stores the data like this:
struct GridSquare target; // Make GridSquare struct to store data
target.xpos = xlinerequested; // Store the xposition the robot was sent to
target.ypos = ylinerequested; // Store the yposition the robot was sent to
target.occupied = IRResult; // Record whether anything was detected by the infra-red detector
Now that seems works all well and good, but when I try to make it an array like it says in the task PDF I keep getting compiler errors...
I've tried using "struct GridSquare[40][40]; // Create 1600 GridSquare objects to use as a map" before the setup(); to initialise but the compiler error I get is "expected unqualified-id before '[' token".
How would I go about changing the struct to an array so I can store the info about each square on the grid?
Thank you
