Question

A class Merger concatenates two positive integers that are greater than 0 and produces a new merged integer.
Example:If the first number is 23 and the second is 764,then the concatenated number will be 23764.
Some of the members of the class are given below:
Classname:Merger
Data members/instance variables:
n1:long integer to store first number
n2:long integer to store second number
mergNum:long integer to store mergednumber
Member functions:
Merger():constructor to initialize the data members
void readNum():to accept the values of the data members n1 and n2
void JoinNum():to concatenate the numbers n1 and n2 and store it in mergNum
void show():to display the original numbers and the merged number with appropriate messages

Specify the class Merger,giving the details of the constructor,void readNum(),void JoinNum() and void show( ) . Define the main() function to create an object and call the functions accordingly to enable the task.
