计算下列函数的值,如果x>-100或x<36,则输出y无定义的信息,要求使用switch语句实现。x+281≤x<1002x+364≤x<81 2x+4 49≤x<64 4x+5 36≤x<49

在使用switch语句实现这个条件判断时,我们需要将`x`的取值范围作为case标签,并在每个分支内检查对应的不等式是否成立。由于题目要求当`x`满足`x > -100` 或 `x < 36` 的时候输出“y无定义”,我们首先需要排除这两个区间。这里是一个基本的伪代码示例:
```csharp
double y;
int x;
// Switch case starts here
switch (true) {
// If x is outside the range [-100, 36] or [49, 64)
case (x <= -100 || x >= 36):
Console.WriteLine("y无定义");
break;
// Check each condition separately
case (x + 281 <= x && x < 1002): // Note that this will never be true for x since x + 281 > x by definition
y = 2 * x + 4; // No need to check further, just output if in correct range
break;
case (x + 364 <= x && x < 81): // Similar, but with different numbers
y = 2 * x + 4;
break;
case (49 <= x && x < 64):
y = 4 * x + 5;
break;
default:
// If none of the above cases match, use a default case to handle it
y = CalculateY(x); // Define this function elsewhere with appropriate logic
}
```
