What is the difference between a static variable and global variable in C/C++?
Are there any specific use cases for using static variables instead of global variables?
Yes, static variables are often used when a function needs to maintain state between calls, but the state shouldn't be accessible from other functions. For example, a counter variable used for tracking how many times a function has been called would be a good candidate for a static variable. Global variables, on the other hand, can be used to share data between multiple functions in a program.
