Difference Between Static Auto Global And Local Variable In The , Difference is static variables are those variables which allows a value to be retained from one call of the function to another But in case of local variables the scope is till the block function lifetime
C What Is Difference Between Static Local Variable method Vs
A local static variable is created once and the method will go out of scope but the static variable is not destroyed and it will live in memory until the program ends A global static variable live in memory until the program ends So what is difference between local and global static variables
7 10 Static Local Variables Learn C LearnCpp, In this lesson we ll explore the use of the static keyword when applied to a local variable Static local variables In lesson 2 5 Introduction to local scope you learned that local variables have automatic duration by default which means they are created at the point of definition and destroyed when the block is exited

What is the correct reason for this performance improvement EDIT I guess I m not being very clear apologies for that What I m trying to say is can according to C spec static variable access be optimized the same way as local variable by Local Variable Vs Static Variable Memory And Performance. You re confusing static and local Variables declared inside a method are local and only exist while that method is invoked Static variables are similar to instance variables except that they belong to the actual Class object rather than a specific instance of the class and hence the SAME variable can be accessed from all instances of the class Local and static in the case you described are synonyms however static is the keyword that you use to make a function local i e private Global functions are not private to the source file they re defined in They can be extern ed to other source files typically by including the header file for the function you want s source file Share
