Description: In C++, the term ‘non-constant’ refers to variables that can be modified after their declaration. Unlike constant variables, which maintain a fixed value throughout their lifetime, non-constant variables allow for assignment and modification of values at any point in the program. This is fundamental in programming, as it is often necessary to store data that changes during the execution of the program, such as counters, accumulators, or the states of an object. Non-constant variables are essential for dynamic data manipulation and allow developers to implement complex logic in their applications. In C++, non-constant variables can be declared using primitive data types, such as integers, floats, and characters, as well as more complex data types like structures and classes. The flexibility they offer is crucial for algorithm development and memory management, as they enable programmers to adapt the behavior of their applications to the changing needs of users or the execution environment.
