Objective-c Common Data Types

Basic Data Type

 

1. int
Output Format: % I, % d, % o % x,

2. Float
Output Format: % F, % E, % G

3. Double
Output Format: % F, % E, % G

4. Char

Output Format character: % C

 

Qualifier:

1. Long
Long INT: % Li
Long double: % lf
To form a long int, add L after the number.
Long int number = 123324123234123l;

2. Long
Long long INT: % llI

3. Short
Short INT: % Hi

4. unsigned

5. Signed

 

The number of bytes each occupies.
