Write a C++ program to illustrate the single inheritance using the banking system as an example.

Write a C++ program to illustrate the single inheritance using the banking system as an example.

Program Algorithm:

Step 1: Include the Header file.

Step 2: Create a forward declaration of a class.

Step 3: Create a new class that has certain member functions and methods.

Step 4: Create the class earlier defined in step 2 and Create it inherit from the class in step 2 using the resolution: operator

Step 5: Now create an object of the sun class and Create it call some methods you defined in step 2.

Program Code:

#include<iostream.h>

class sav_acct

class account

{

char cust_name[20];

int acc_no;

char acc_type[20];

public:

int get_accinfo()

{

cout<<"\n\nEnter customer name:-";

cin>>cust_name;

cout<<"\n\nEnter Account no:-";

cin>>acc_no;

cout<<"\n\nEnter Account type:-";
