Variable
Definition:
A named storage location in memory for data, which has a type.
Detailed Explanation
- A variable represents a named reference to a value in memory.
- It allows programs to store, retrieve, and manipulate data.
- Variables must usually be declared before use, with their type defining what values they can hold.
- Common pitfalls include using uninitialized variables or assuming they hold data after scope ends.
Example
// Example of declaring and using a variable in a generic language // let age = 25; // print(age);
