Objective-C 算术运算符

下表显示了 Objective-C 语言支持的所有算术运算符。假设变量 A 为 10，变量 B 为 20，则

运算符	描述	实例
+	将两个操作数相加	A + B = 30
-	从第一个操作数中减去第二个操作数	A - B = -10
*	将两个操作数相乘	A * B = 200
/	将分子除以分母	B / A = 2
%	模算子和整数除法后的余数	B % A = 0
++	增量运算符将整数值增加一	A++ = 11
—	减量运算符将整数值减少一	A— = 9

实例

尝试以下实例以了解 Objective-C 编程语言中可用的所有算术运算符:

#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 );
}

运行一下

结果如下:

2022-07-07 22:10:27.005 demo[25774] Line 2 - Value of c is 11
2022-07-07 22:10:27.005 demo[25774] Line 3 - Value of c is 210
2022-07-07 22:10:27.005 demo[25774] Line 4 - Value of c is 2
2022-07-07 22:10:27.005 demo[25774] Line 5 - Value of c is 1
2022-07-07 22:10:27.005 demo[25774] Line 6 - Value of c is 21
2022-07-07 22:10:27.005 demo[25774] Line 7 - Value of c is 22
