Scope of the variable is defined as the area in the program where variable is callable.
In C language scope of variable depends on the type of variable like :
1. local variable
2. global variable
-In case of local variable, scope is limited upto that body or function in which variable was defined.
-You can not call the variable after the function body.
-In case of global variable, scope is increased
-and we can excess that variable anywhere in the program.
