#import "AppController.h"

@implementation AppController
- (IBAction)Calculateid)sender {
if (Fiber >= 4){

Fiber = 4;
}
Points = ( Calories / 50 ) + ( Fat / 12 ) - ( Fiber / 5 );
}
@end

I'm trying to make a Weight Watchers calculator and I keep coming up with errors. I'm not sure what I'm doing wrong....

I'm getting errors after if (Fiber >= 4){ saying warning: comparison between pointer and integer

Also getting errors after Fiber = 4; saying warning: assignment makes pointer from integer without a cast

And last errors after Points = ( Calories / 50 ) + ( Fat / 12 ) - ( Fiber / 5 ); saying error: invalid operands to binary /

Any help would be grateful. Thank you.

What data type are the Fiber, Points, etc? Like NSNumber, int?

from the warnings and errors, I'd say Fiber is declared as a int * instead of int. If it is a pointer and needs to be you need to dereference Fiber before using its value in an expression.

Fiber, Points, etc are what the textfields are called under outlets...not sure if that answers your question.

Okay, I understood what you meant I got now...

#import "AppController.h"

@implementation AppController
- (IBAction)Calculateid)sender {
double iCal, iFat, iFiber, iPoints;
iCal = [Calories doubleValue];
iFat = [Fat doubleValue];
iFiber = [Fiber doubleValue];
if (iFiber > 4)
iFiber = 4;
iPoints = (Calories / 50) + (Fat / 12) - (Fiber / 5);
}
@end

Everything runs fine except I get an error for the iPoints = (Calories / 50) + (Fat / 12) - (Fiber / 5); line

You should use iCal iFiber etc in that final calculation.

Oh, okay I got it. Thanks everyone.

Assignment makes integer from pointer without a cast

Hi,
In Objective-c, I have one function which accepts int as parameter, viz:
-(void)Sumint)i{
Sum = i+10;
}

where 'Sum' is static variable declared globally, int he same .m file.
now, I am calling this 'Sum' function from some other function as follows:
-(void)Funct{
int i = 10;
[self Sum:i];
}

After **[self Sum:i];** i get warning saying:
"assignment makes integer from pointer without a cast"


I am not getting where is the mistake. Please let me know as soon as possible.

Thanx.
