It's simple. A global variable has a scope through out out the C program. It can be accessed anywhere from any function or etc. A local variable on the other hand, is local to it's container only and can not be accessed outside of it's container. For example a function has variable sum then sum is only accessible within the function and not anywhere else.
True, a variable cannot be both global and local. But if a global and a local variable share the same name, the local one will hide the global.
'global static'?! There is no such thing.
A local variable is a variable declared inside a construct, such as a class or function, while a global variable is a variable declared outside of any construct.
A variable declared static outside of a function has a scope the of the source file only. It is not a global variable. A variable declared outside of a function and without the static qualifier would be a global variable.
When you acess a global variable inside main function you must use the same name, because the variable declared as global can be accessed by any function/procedure on the class where it was defined.
A static variable is a variable allocated in static storage. A local variable is a variable declared inside a function. A global variable is a variable declared outside of any class or function. Note that local variables and global variables can both be allocated in static storage.
The accessibility. The global one: almost everywhere in the code may reference to the global variable directly. The private variable, is private to the declaring module (class, method, assembly) only. Outside of that module has no access to it directly.
the difference between global and international strategy
what is the difference between international communication and global communication
Static may be local of global -local static variable is limited to the function scope. and retain it's value when function is been called . compiler differentiate static variables with a prefix function name while dealing with same name static variable in different functions. - Global static variable is visible to all the function defined in the file and retain it value but it cannot be used outside this file. now Global Variable --- this variable is also visible to all of the functions inside the file but also can be used outside the file via extern keyword.
True, a variable cannot be both global and local. But if a global and a local variable share the same name, the local one will hide the global.
Global variables are non-local variables. That is, variables that are not defined in a function or class. They are globally accessible to all code in the same translation unit. External variables are global variables that have external linkage; they are accessible across translation units.
essential diffrence between global and local optimization
There is no difference between the two. The global depletion of ozone is the hole over ozone only.
'global static'?! There is no such thing.
what is the difference between global politics and international politics
Variable declared inside declaration part is treated as a global variable, which means after translation of jsp file into servletthat variable will be declared outside the service method as an instance variablethe scope is available to the complete jspVariable declared inside a scriplet will be declared inside a service method as a local variable and the scope is with in the service method.
