Pascal - 算术运算符

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

以下示例说明了算术运算符 -

program calculator;
var
a,b,c : integer;
d: real;

begin
   a:=21;
   b:=10;
   c := a + b;
   
   writeln(' Line 1 - Value of c is ', c );
   c := a - b;
   
   writeln('Line 2 - Value of c is ', c );
   c := a * b;
   
   writeln('Line 3 - Value of c is ', c );
   d := a / b;
   
   writeln('Line 4 - Value of d is ', d:3:2 );
   c := a mod b;
   
   writeln('Line 5 - Value of c is ' , c );
   c := a div b;
   
      writeln('Line 6 - Value of c is ', c );
end.

请注意，Pascal 是一种强类型编程语言，因此如果您尝试将除法结果存储在整数类型变量中，则会出现错误。当上面的代码被编译并执行时，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 d is 2.10
Line 5 - Value of c is 1
Line 6 - Value of c is 2
