Question

After it is defined, a variable holds one value which cannot be re-written?

1) True
2) False

Answer 1

A variable in computer science can hold different values at different times and can be overwritten.

Step-by-step explanation:

The statement that after a variable is defined, it holds one value which cannot be re-written is False in computer science.

In computer science, a variable is a named storage location that can hold different values at different times. Once assigned, the value of a variable can be changed or overwritten, which is a fundamental feature of variables in programming languages.

For example, in Python, you can define a variable and assign it a value like this:

my_variable = 10

Later, you can reassign a different value to the same variable:

my_variable = 20

In this case, the earlier value of 10 is overwritten by the new value of 20.
