D 编程 - D 中的算术运算符


下表列出了 D 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 -

操作员 描述 例子
+ 它添加了两个操作数。 A + B 得出 30
- 它从第一个操作数中减去第二个操作数。 A - B 给出 -10
* 它将两个操作数相乘。 A * B 给出 200
/ 它将分子除以分母。 B / A 给出 2
% 它返回整数除法的余数。 B % A 给出 0
++ 增量运算符将整数值加一。 A++ 给出 11
-- 递减运算符将整数值减一。 A-- 给出 9

例子

尝试以下示例来了解 D 编程语言中可用的所有算术运算符 -

import std.stdio; 
 
int main(string[] args) { 
   int a = 21; 
   int b = 10; 
   int c ;  
   
   c = a + b; 
   writefln("Line 1 - Value of c is %d\n", c ); 
   c = a - b; 
   writefln("Line 2 - Value of c is %d\n", c ); 
   c = a * b; 
   writefln("Line 3 - Value of c is %d\n", c ); 
   c = a / b; 
   writefln("Line 4 - Value of c is %d\n", c ); 
   c = a % b; 
   writefln("Line 5 - Value of c is %d\n", c ); 
   c = a++; 
   writefln("Line 6 - Value of c is %d\n", c ); 
   c = a--; 
   writefln("Line 7 - Value of c is %d\n", c ); 
   char[] buf; 
   stdin.readln(buf); 
   return 0; 
}

当您编译并执行上述程序时,它会产生以下结果 -

Line 1 - Value of c is 31
  
Line 2 - Value of c is 11
  
Line 3 - Value of c is 210 
 
Line 4 - Value of c is 2 
 
Line 5 - Value of c is 1 
 
Line 6 - Value of c is 21
  
Line 7 - Value of c is 22
