objective-c synthesizeing leads to error?

I m pretty new to objective-c, and trying some examples on my own. Here is my sample code

#import <objc/objc.h>
#import <Foundation/Foundation.h>


@interface Test:NSObject
{
  int noOfWheels;
  int total;
}

   @property int noOfWheels;
   @property int total;
   -(void) print;
@end

@implementation Test
@synthesize  noOfWheels, total;
-(void) print
{
  NSLog (@" noofWheels is %i, total %i ", noOfWheels, total);
}

@end

int main ( int argc, char ** argv)
{
  Test *t = [Test alloc];
  t = [t init];
  [t setnoOfWheels: 10];
  [t settotal: 300];
  [t print];
}

and it compiled with no error, but when i run the program i get the following error.

Uncaught exception NSInvalidArgumentException, reason: -[Test setnoOfWheels:]: unrecognized selector sent to instance 0x87aef48

What am i doing wrong in my code ?

[t setnoOfWheels: 10];

should be

[t setNoOfWheels: 10];

or even better, since you're declaring a property:

t.noOfWheels = 10;

By default 1st letter of iVar is capitalized in setter method name. So correct call will be:

[t setNoOfWheels: 10];
