Arithmetic Operators in Objective-C
Following table shows all the arithmetic operators supported by Objective-C language. Assume variable A holds 10 and variable B holds 20, then −
| Operator | Description | Example |
|---|---|---|
| + | Adds two operands | A + B will give 30 |
| - | Subtracts second operand from the first | A - B will give -10 |
| * | Multiplies both operands | A * B will give 200 |
| / | Divides numerator by denominator | B / A will give 2 |
| % | Modulus Operator and remainder of after an integer division | B % A will give 0 |
| ++ | Increment operator increases integer value by one | A++ will give 11 |
| -- | Decrement operator decreases integer value by one | A-- will give 9 |
Example
Try the following example to understand all the arithmetic operators available in Objective-C programming language −
#import <Foundation/Foundation.h>
int main() {
int a = 21;
int b = 10;
int c ;
c = a + b;
NSLog(@"Line 1 - Value of c is %d\n", c );
c = a - b;
NSLog(@"Line 2 - Value of c is %d\n", c );
c = a * b;
NSLog(@"Line 3 - Value of c is %d\n", c );
c = a / b;
NSLog(@"Line 4 - Value of c is %d\n", c );
c = a % b;
NSLog(@"Line 5 - Value of c is %d\n", c );
c = a++;
NSLog(@"Line 6 - Value of c is %d\n", c );
c = a--;
NSLog(@"Line 7 - Value of c is %d\n", c );
}
When you compile and execute the above program, it produces the following result −
2013-09-07 22:10:27.005 demo[25774] Line 1 - Value of c is 31 2013-09-07 22:10:27.005 demo[25774] Line 2 - Value of c is 11 2013-09-07 22:10:27.005 demo[25774] Line 3 - Value of c is 210 2013-09-07 22:10:27.005 demo[25774] Line 4 - Value of c is 2 2013-09-07 22:10:27.005 demo[25774] Line 5 - Value of c is 1 2013-09-07 22:10:27.005 demo[25774] Line 6 - Value of c is 21 2013-09-07 22:10:27.005 demo[25774] Line 7 - Value of c is 22
