To solve the problem of declaring an integer variable [tex]\( x \)[/tex] and setting it equal to 17, we need to understand the syntax for variable declaration in most programming languages, specifically those that are statically typed such as C or C++.
1. We need to create a variable called [tex]\( x \)[/tex].
2. We need to specify that [tex]\( x \)[/tex] is of type integer.
3. We need to assign the value 17 to [tex]\( x \)[/tex].
Let's analyze each option given:
1. [tex]\( x = 17; \)[/tex]
- This simply assigns 17 to [tex]\( x \)[/tex] without specifying that [tex]\( x \)[/tex] is an integer variable. This would work in dynamically typed languages like Python, but typically require a type declaration in statically typed languages.
2. [tex]\( \text{int} \, 17 = x; \)[/tex]
- This is incorrect syntax because it tries to assign [tex]\( x \)[/tex] to the value 17, and it places `int` before the value instead of the variable name.
3. [tex]\( \text{int} \, = 17; \)[/tex]
- This is incorrect syntax because it lacks a variable name. It tries to declare a variable of type `int` while only providing the value 17.
4. [tex]\( 17 = x; \)[/tex]
- This is incorrect because it is trying to assign [tex]\( x \)[/tex] to the value 17, which is invalid syntax as the variable should be on the left side.
5. [tex]\( \text{int} \, x = 17; \)[/tex]
- This syntax correctly declares [tex]\( x \)[/tex] as an integer and assigns the value 17 to it.
Thus, the correct choice is:
[tex]\[ \text{int} \, x = 17; \][/tex]
Therefore, the answer to the question is choice number [tex]\( 5 \)[/tex].
