NSInteger problem

Question

How to use the NSInteger give example and simplecode

Answer 1

NSInteger is defined like this:

#if __LP64__ || NS_BUILD_32_LIKE_64
  typedef long NSInteger;
  typedef unsigned long NSUInteger;
#else
  typedef int NSInteger;
  typedef unsigned int NSUInteger;
#endif

It's the same as int on 32Bit or long on 64Bit.

Answer 2

NSInteger a, b, c;

a = 2;
b = 40;

c = a + b;

NSLog(@"THE answer is: %d\n", c);
