D 编程 - 逻辑运算符

下表显示了 D 语言支持的所有逻辑运算符。假设变量A的值为 1，变量B的值为 0，则：

示例

尝试以下示例以了解 D 编程语言中可用的所有逻辑运算符：

import std.stdio;

int main(string[] args) {
   int a = 5;
   int b = 20;
   int c ;

   if ( a && b ) {
      writefln("Line 1 - Condition is true\n" );
   }
   if ( a || b ) {
      writefln("Line 2 - Condition is true\n" );
   }
   /* lets change the value of a and b */

   a = 0; 
   b = 10; 

   if ( a && b ) { 
      writefln("Line 3 - Condition is true\n" ); 
   } else { 
      writefln("Line 3 - Condition is not true\n" ); 
   } 
   
   if ( !(a && b) ) { 
      writefln("Line 4 - Condition is true\n" ); 
   } 
   return 0;
}

编译并执行上述程序后，将产生以下结果：

Line 1 - Condition is true 
 
Line 2 - Condition is true
  
Line 3 - Condition is not true
  
Line 4 - Condition is true
