Hi, i’m new working with this gorgeous book and, I like if you have time to review if my code is well developed and according with the proposal of the challenge.
[code]#import <Foundation/Foundation.h>
@interface BNRStockHolding : NSObject
{
float _purchaseSharePrice;
float _currentSharePrice;
int _numberOfShares;
}
-
(float)purchaseSharePrice;
-
(void)setPurchaseSharePrice:(float)p;
-
(float)currentSharePrice;
-
(void)setCurrentSharePrice:(float)c;
-
(int)numberOfShares;
-
(void)setNumberOfShares:(int)n;
-
(float)costInDollars; // purchaseSharePrice * numberOfShares
-
(float)valueInDollars; // currentSharePrice * numberOFShare
@end[/code]
[code]#import “BNRStockHolding.h”
@implementation BNRStockHolding
-
(float)purchaseSharePrice
{
return _purchaseSharePrice;
} -
(void)setPurchaseSharePrice:(float)p
{
_purchaseSharePrice = p;
} -
(float)currentSharePrice
{
return _currentSharePrice;
} -
(void)setCurrentSharePrice:(float)c
{
_currentSharePrice = c;
} -
(int)numberOfShares
{
return _numberOfShares;
} -
(void)setNumberOfShares:(int)n
{
_numberOfShares = n;
} -
(float)costInDollars
{
return _purchaseSharePrice * _numberOfShares;
} -
(float)valueInDollars
{
return _currentSharePrice * _numberOfShares;
}
@end[/code]
