Write some "set" functions for the triangle type and use them to initialize the triangle.
/* set point "num" of tri to (x, y) */
void setTriangleModPoint( TriangleMod *tri, int num, int x, int y)
{
}
/* set the color of tri to (r, g, b) */
void setTriangleModColor( TriangleMod *tri, int r, int g, int b)
{
}
int main()
{
TriangleMod *trimod = newTriangleMod();
/* Initialize trimod here */
setTriangleModPoint( trimod, 0, 45, 97 );
setTriangleModPoint( trimod, 1, 75, 80 );
setTriangleModPoint( trimod, 2, 0, 0 );
setTriangleModColor( trimod, 120, 240, 50);
/* Print out trimod */
printTriangleMod( trimod );
/* Free memory */
freeTriangleMod( trimod );
}
