Solution

To declare and initialize a variable x with the value 5 in C or similar programming languages, the correct syntax would be:

  • int x = 5;

Analysis of Options:

  1. int x, x=5 - Incorrect syntax as it tries to declare x twice.
  2. int x=5 - Correct, this both declares and initializes x.
  3. x = 5 - Incorrect as this is just an assignment and assumes x was declared beforehand.
  4. declare x=5 - Incorrect syntax, as "declare" is not a keyword in standard programming languages.

Final Answer:

The correct way to declare and initialize a variable x with the value 5 is: int x = 5;
