Question

How can you change this function from the main program “struct point” to a “class point” into new .h and .cpp projects. Make all the member variables private. Add getter and setter methods for each member variable.

/////////////////////////////////////////////////

struct point
{ int x,y;};

int main()
{

point plat[20];
for (int i=0;i<10;i++) {

  plat[i].x=rand()%400;
plat[i].y=rand()%533;
}
