Explam Local Data and Global Data or variable in C++ using examples.

(1) Local data or variable is that data which comes inside the class.
(2) Global data or variable that data which comes outside the class.
(3) So, For accessing global data, the compiler requires a scope resolution operator.
(4) While in local data, scope resolution is not required.

int a ; //global data
void main()
{
int a; // local data
}
