c programming static variable example
In C, variables are always statically (or lexically) scoped i.e., binding of a variable can be determined by program text and is independent of the run-time function call stack.
How do you write a static variable?
Static variable
If a variable is static , the variable is assigned memory once and all objects of the class access the same variable.
A static variable can be created by adding the static keyword before the variable during declaration.
What is static function in C with example?
In C programming language, a static function can be defined as one that has its scope limited to the file in which it is declared.
This means that you cannot access the same from any other files in the program.
However, you can still call a static function multiple times with the same file.
What is static variable in C with example?
.
1) A static int variable remains in memory while the program is running.
A normal or auto variable is destroyed when a function call where the variable was declared is over.
For example, we can use static int to count the number of times a function is called, but an auto variable can't be used for this purpose.16 juil. 2023
