Description: Lifetime analysis in C++ refers to the study of how long variables exist and their scope within a program. This concept is fundamental in programming as it determines the duration of variable existence and their accessibility in different parts of the code. In C++, variables can have different lifetimes, classified as automatic, static, and dynamic. For instance, automatic variables are created and destroyed within the scope of a function, while static variables persist throughout the program’s execution. On the other hand, dynamic variables are managed through dynamic memory, allowing their creation and destruction at runtime using operators like ‘new’ and ‘delete’. Understanding lifetime analysis is crucial to avoid errors such as memory leaks and invalid memory accesses, which can lead to unexpected behaviors in the program. Furthermore, this analysis helps optimize resource usage and improve code efficiency, enabling programmers to manage memory and application performance effectively.
