Explanation of Solution
Static member variable:
In object-oriented
- The keyword "static" means in memory there is only one copy of the static member variable is available.
- If no initialization is present, all static variables are set to zero when the first object is created.
- The static member variables are defined outside of the class declaration, even though it is in the class. The static member variables are used anywhere in the program.
Example:
Consider the example of static member variable declaration is as follows:
//Header file
#include<iostream>
using namespace std;
//class definition
class sample
{
//declaration of instance variable
int c;
//declaration of static variable
static int ct;
//access specifier
public:
//constructor
sample()
{
//increment the variable
c = ++ct;
}
//function definition
void show_code()
{
//display the output
cout << "Object number is: " << c << endl;
}
