程序运算结果的写法主要取决于所使用的编程语言和具体的运算环境。以下是一些常见编程语言中如何表示程序运算结果的示例:
Pascal :```pascal
program Example;
var
s: string;
r: real;
pi: real;
begin
s := 'let us begin';
r := 3;
pi := 3.14159;
writeln(s);
writeln('Area is:', pi * r * r:10);
writeln('Area=', pi * r * r:10:3);
end.
```
Delphi
:
```delphi
program Example;
var
a, b, c, d: integer;
begin
a := 5;
b := 6;
c := a + Sqr(b);
a := c mod b;
b := a + b;
writeln(Sqr(a));
writeln('b=', b);
writeln('c=', c);
writeln('d=', a + b + c);
writeln(Abs(5 - c));
end.
```
C:
```c
include int main() { float x, y; scanf("%f", &x); if (x > 0.0) y = 0.0; else if ((x < 5.0) && (x != 2.0)) y = 1.0 / (x + 2.0); else if (x > 10.0) y = 10.0; printf("%f\n", y); return 0; } ``` Java: ```java public class Test { public static void main(String[] args) { int num = 0; while (num <= 2) { num++; System.out.println(num); } } } ``` C++: ```cpp include using namespace std; int main() { int a = 1, b = 1; for (; a <= 100; a++) { if (b == 20) break; if (b % 3 == 1) { b += 3; continue; } b -= 5; } cout<< a << endl; return 0; } ``` 建议 明确输出格式: 在编写程序时,应明确输出结果的格式,以便于阅读和理解。 使用合适的格式化输出 测试和验证:在编写程序后,应进行充分的测试和验证,确保运算结果的正确性。 希望这些示例和建议对你有所帮助!
