Hardcoding an array in RobotC

I'm having some trouble declaring an array in RobotC.

I have a struct definition:


	Code: struct waypoint { int index; int x; int y; int reachable_points[4]; int counter; int BFSrank; bool visited; } waypoint;

and when I try to initialize an array for reachable_points:


	Code: waypoint one; one.index = 1; one.x = 9; one.y = 6; one.reachable_points = {2, -1, -1, -1}; one.visited = false; one.BFSrank = -1;

The line containing the array initialization breaks, along with everything after it. If I replace the curly braces with square braces, the line remains broken, but everything after it is fine. How should I go about declaring the array?

Re: Hardcoding an array in RobotC

This works ok:


	Quote: struct waypoint { int index; int x; int y; int *reachable_points; int counter; int BFSrank; bool visited; } waypoint; task main() { waypoint one; int foo[4] = {2, -4, -5, -1}; one.index = 1; one.x = 9; one.y = 6; one.reachable_points = &foo; one.visited = false; one.BFSrank = -1; writeDebugStreamLine("one.reachable_points[0]: %d", one.reachable_points[0]); writeDebugStreamLine("one.reachable_points[1]: %d", one.reachable_points[1]); writeDebugStreamLine("one.reachable_points[2]: %d", one.reachable_points[2]); writeDebugStreamLine("one.reachable_points[3]: %d", one.reachable_points[3]); }
