Function Template is a mechanism by which you can write
generic programs.Means you only need to create one framework
and based on your requirement you can write many
implementations.

one Framework is called Function Template.
Each implementation(function call) is called Template
Functions.
For your reference see the example below..

EX:

template <class T>
void swap(T &a,T &b) <----//This is Function Template.
{ T temp;
temp = a;
a = b;
b = temp;
}

int main()
{
int i1 = 5,i2 = 6;
float f1 = 2.2,f2 = 5.5;
char c1 = 'A',c2 = 'B';

cout<<"Before swapping i1 ="<<i1<<" i2 ="<<i2;
swap(i1,i2); <-----//This is 1 Template Function
cout<<"After swapping i1 ="<<i1<<" i2 ="<<i2;
cout<<"Before swapping f1 ="<<f1<<" f2 ="<<f2;
swap(f1,f2); <-----//This is 2 Template Function
cout<<"After swapping f1 ="<<f1<<" f2 ="<<f2;
cout<<"Before swapping c1 ="<<c1<<" c2 ="<<c2;
swap(c1,c2); <-----//This is 3 Template Function
cout<<"After swapping c1 ="<<c1<<" c2 ="<<c2;

return 0;
}

Objective The objective of this problem is to test the understanding of Object-Oriented Programming (OOP) concepts, in particular, on encapsulation. Problem Description Create a program for managing customer’s bank accounts. A bank customer can do the following operations: 1. Create a new bank account with an initial balance. 2. Deposit money into his/her account. 3. Withdraw money from his/her account. For this operation, you need to output “Transaction successful” if the intended amount of money can be withdrawn, otherwise output “Transaction unsuccessful” and no money will be withdrawn from his/her account. Input The input contains several operations and is terminated by “0”. The operations will be “Create name amount”, “Deposit name amount”, or “Withdraw name amount”, where name is the customer’s name and amount is an integer indicating the amount of money. There will be at most 100 bank accounts and they are all created on the first month when the bank is opening. You may assume that all account holders have unique names and the names consist of only a single word. Output The output contains the transaction result of withdrawal operations and the final balance of all customers after some withdrawal and deposit operations (same order as the input). Sample Input Create Billy 2500 Create Charlie 1000 Create John 100 Withdraw Charlie 500 Deposit John 899 Withdraw Charlie 1000 0
