What is the file scope of a static variable in C?
The global static variable is accessible by all the functions in the same source file as the variable. This variable has a File Scope , i.e., we can access the variable anywhere in the same C file. Therefore, the variables with File Scope do not conflict with other variables because they are private to the source file.What is the file scope of a static variable?
The scope of static automatic variables is identical to that of automatic variables, i.e. it is local to the block in which it is defined; however, the storage allocated becomes permanent for the duration of the program.How to use static variable in different file in C?
3.1.
Static variables in C have the following two properties: They cannot be accessed from any other file. Thus, prefixes “ extern ” and “ static ” cannot be used in the same declaration. They maintain their value throughout the execution of the program independently of the scope in which they are defined.- In computer programming, a static variable is a variable that has been allocated "statically", meaning that its lifetime (or "extent") is the entire run of the program.
