Question
![Suppose `Calsomething` is an overloaded method. The declarations of the `Calsomething` methods are shown below. Assume there is sensible code within the curly brackets.
1. `int Calsomething (int[] a) { … }`
2. `int Calsomething (int a) { … }`
3. `int Calsomething (int a, double b) { … }`
4. `int Calsomething (double a) { … }`
5. `int Calsomething (int a, int b []) { … }`
6. `int Calsomething (double a, double b) { … }`
7. `int Calsomething (double[] a, double[] b) { … }`
8. `int Calsomething (int[] a, int b, int c) { … }`
9. `int Calsomething (int a, int[] b, int c) { … }`
10. `int Calsomething (int a, int b, double c) { … }`
11. `int Calsomething (int a, double b, int[] c) { … }`
12. No corresponding method definition
Consider the snippet of code below:
```java
int a = 11, b = 22, c = 0;
double x = 1.5, y = 5.8;
int[] iarr = new int[99];
double[] darr = new double[99];
```

![```plaintext
___ a = CalSomething (a, CalSomething(a), y);
```
### Explanation
This line of code appears to be a part of a programming language statement where a variable `a` is being assigned a value. The function `CalSomething` is called with three parameters: `a`, the result of `CalSomething(a)`, and `y`.
- **Underscore Placeholder:** The underscore (`___`) at the beginning suggests that a keyword or an operator like `int`, `var`, `let`, or `const` might be missing in a programming language context. This would typically be the type declaration (e.g., `int`, `var`) or an operator (e.g., `+=`).
- **Function `CalSomething`:** This function takes multiple arguments. It is called twice:
1. The first argument is the variable `a`.
2. The second argument is a nested function call `CalSomething(a)`, which implies recursion or repeated operations.
3. The third argument is a variable `y`.
This line of code may be used as an example in programming exercises to demonstrate concepts like function calling, recursion, or working with multiple arguments.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F0f6dc858-dc6a-4614-8154-d70dfca22707%2F1e42f6ca-39a7-4161-9c30-7a19f248c619%2Fnwaayufq_processed.jpeg&w=3840&q=75)
