Question
What is wrong with the code below? (Choose all that apply) int guess = 42.07; Group of answer choices You cannot store a double in an int variable. The variable should be a String. Nothing the code is fine as-is. The type should be “Double” not “int”. The type of the variable should be a float or a double. You cannot store an int in a double variable.

In the provided code snippet, `int guess = 42.07;`, there are several issues. Here is the analysis of each option:
1. **You cannot store a double in an int variable.** - **True**. The value `42.07` is a double (or floating-point) value, and it cannot be directly stored in an `int` variable, as it would result in a loss of the decimal part.
2. **The variable should be a String.** - **False**. While you could theoretically store a representation of the number as a String, it’s not a requirement for storing the value `42.07`. The variable type depends on the intended use (integer or floating point).
3. **Nothing the code is fine as-is.** - **False**. The code has a type mismatch error, as you cannot assign a double value to an int without explicit casting.
4. **The type should be “Double” not “int”.** - **True**. If you want to store the value `42.07`, you should use a `double` (or `float`), not an `int`.
5. **The type of the variable should be a float or a double.** - **True**. Since `42.07` is a decimal number, you should use either `float` or `double` type for the variable to accurately represent this number.
6. **You cannot store an int in a double variable.** - **False**. You can indeed store an integer value in a double variable, as doubles can represent both whole numbers and decimal values.
In summary, the correct options are:
- You cannot store a double in an int variable.
- The type should be “Double” not “int”.
- The type of the variable should be a float or a double.
