Solutions: If Else Statements and the Ternary Operator

If/else exercise:

- (NSString *) itemMaryCanPurchaseForDollars:(NSInteger)dollars {
    NSString *itemToReturn;

    if (dollars >= 100000000) {
        itemToReturn = @"have The Big Apple";
    } else if (dollars >= 1000) {
        itemToReturn = @"have an Apple computer";
    } else if (dollars >= 6) {
        itemToReturn = @"have an apple";
    } else if (dollars >= 5) {
        itemToReturn = @"have some gum";
    } else {
        itemToReturn = @"get out of my store";
    }
    
    NSLog(@"For $%d, Mary can: %@", dollars, itemToReturn);
    return itemToReturn;
}
