In this case, the variable is initialized only once at compile time and keeps its state during the whole program execution including multiple function invocations The static variable now acts similar to a global variable, which keeps its state, but is only visible to the block in which it was defined
epc fasselt c keywords report
A static variable declared outside a function definition has its scope restricted to the file where it is declared Due to their global lifetimes, the compiler detects all static and global variables during program compilation and allocates them space in the data area of the process address space
cases
External/global variables have file scope and static storage duration static used in a block means that the variable lives beyond the duration of the block, and is initialized only once informs the compiler that i is an int variable, but doesn't cause it to allocate space You can define new types using typedef

When you begin to split up your C program into multiple files you need header files to store function and type declarations. void add(int); int isEmpty();.

What is static variable in C programming?
A static variable possesses the property of preserving its actual value even after it is out of its scope. Thus, the static variables are able to preserve their previous value according to their previous scope, and one doesn't need to initialize them again in the case of a new scope.What is static variable with example?
Any variable when declared with the keyword “static” is known as static variable or class variable in JAVA. Static variable is used to fulfill the common properties of all objects. For example: institute name of students is common for all students so it will be declared as static variable in JAVA.How to use static in C programming?
A static function in C is a function that has a scope that is limited to its object file. This means that the static function is only visible in its object file. A function can be declared as static function by placing the static keyword before the function name.- The static keyword in C is a storage class specifier. It has different meanings based on the context. Within a function, it makes the variable retain its value among multiple function calls. Outside of a function, it restrains the visibility of the variable or function to the current file.
