What is the use of the `v` variable in the following code: `int v = 5;`?
The variable `v` is just a placeholder for the value `5` and does not perform any significant function in the program.
Thatâ€™s incorrect. The variable `v` is crucial for storing data and can be used later in the program.
Can you describe how a variable like `v` can be used for calculations or in a loop?
