//----@interface part----

@interface Coordinate : NSObject


-(void) setCoordinate_X: (int) x;
-(void) setCoordinate_Y: (int) y;
-(int)  getCoordinate_X;
-(int)  getCoordinate_y;


@end

//----@implementation part----

@implementation Coordinate

{
    int c_X;
    int c_Y;
}



-(void) setCoordinate_X:(int)x
{
    c_X=x;
}

-(void) setCoordinate_Y:(int)y
{
    c_Y=y;
}

-(int) getCoordinate_X
{
    return c_X;
}

-(int) getCoordinate_y
{
    return c_Y;
}
@end

//---- Program part ----

int main(int argc, const char * argv[])
{

    @autoreleasepool {
        
        Coordinate *myCoordinate=[Coordinate alloc];
        myCoordinate=[myCoordinate init];
        
        
        
        //Set coordinate
        
        [myCoordinate setCoordinate_X:100];
        [myCoordinate setCoordinate_Y:200];
        
        //Print coordinate
        NSLog(@"The coordinate is (%i,%i)",[myCoordinate getCoordinate_X],[myCoordinate getCoordinate_y]);
        
               
        
    }
    return 0;
