How to select a storage class What Is Scope? The scope of a variable refers to the extent to which different parts of a program have access to the variable--in other words, where the variable is visible. When referring to C variables, the terms accessibility and visibility are used interch...
Types of Storage Classes in C There are four classes in C programming language, Automatic storage classes Register storage classes Static storage classes External storage classes 1) Automatic storage classes The keywordautois used to declare variable of automatic storage class. (keyword auto is optiona...

Every variable in C programming has two properties: type and storage class. Type refers to the data type of a variable. And, storage class determines the scope, visibility and lifetime of a variable. There are 4 types of storage class: ...
There are 4 types of storage classes in C: auto register extern static 1. auto It is the default storage class for every local variables. When a function is called they are created and when the function exits they are destroyed automatically. Example void main(){ int data; auto int data...
At least a few of these will look familiar to anyone who has done a cursory amount of Objective-C programming. Let’s go into more detail with each one: auto There’s a good chance you’ve never seen this keyword in the wild. That’s becauseautois the default storage class, and ther...
In order to designate a storage class, you preface the variable type by the name: //static variable static int score = 0; Automatic The auto keyword is one you will never really see in code, because it is implied. An auto variable is defined within functions, and they allocate memory ...
In C programming, whenstaticis used on a global variable, it causes only one copy of that member to be shared by all the objects of its class. Example of static Storage Class The following example demonstrates the use of a static storage class in a C program − ...
Storage Classes in C++ - A storage class defines the scope (visibility) and life-time of variables and/or functions within a C++ Program. These specifiers precede the type that they modify. There are following storage classes, which can be used in a C++
