Register is an entity which can hold a maximum of 100 names. The register enables the user to add and remove names from the top most end only. Define a class Register with the following details: Class name : Register Data members / instance variables: stud[ ] : array to store the names of the students cap : stores the maximum capacity of the array top : to point the index of the top end Member functions: Register (int max) : constructor to initialize the data member cap = max, top = −1 and create the string array void push(String n) : to add names in the register at the top location if possible, otherwise display the message “OVERFLOW” String pop( ) : removes and returns the names from the top most location of the register if any, else returns “\$\$” void display( ) : displays all the names in the register

void push(String n)
{
    if (top == cap - 1)
        System.out.println("OVERFLOW");
    else
    {
        top++;
        stud[top] = n;
    }
}

String pop()
{
    if (top == -1)
        return "$$";
    else
    {
        String val = stud[top];
        top--;
        return val;
    }
}
