Question

so I need to divide on variable by a number. How can I do this? I know about the C functions of DIV and MOD, but do not know how to use them in objective-C/cocoa-touch. Heres an example of my code.

// hide the previous view
scrollView.hidden = YES;

//add the new view
scrollViewTwo.hidden = NO;

NSUInteger across;
int i;
NSUInteger *arrayCount;
// I need to take arrayCount divided by three and get the remainder

When I try to use / or % I get the error "Invalid operands to binary expression ( NSUInteger and int) Thanks for any help

Answer 1

首先,arrayCount是否真正成为点?

任何方面,如果是<条码>,则。您只是要指出这一点......

NSInteger arrayCountValue = *arrayCount;

......并使用<条码>/(供司使用)和<条码>%(取用模块):

NSInteger quotient = arrayCountValue / 3;
NSInteger rest = arrayCountValue % 3;

如果没有辅助变量,你也可以这样做:

NSInteger quotient = *arrayCount / 3;
NSInteger rest = *arrayCount % 3;

仅删除参考操作人*>。不是要点:

NSInteger quotient = arrayCount / 3;
NSInteger rest = arrayCount % 3;
