    What is a variable in programming?
    At the most fundamental level, a variable can be seen as a storage box in the memory of a computer. This box can hold different types of values, which can be retrieved or changed as needed. The computer uses the variable’s name as an address to access its content. In programming, we assign values to variables using an equals sign (=).
