C++ Classes and Objects Program!!

[Ravi149]

Hi Friends,
How are you? Good Morning!
I am getting o/p for below C++ program(using genaral C++ arrays , flow statements, and functions).But i want to develope this program on Classes, Objetcs and Functions etc? Please let me know the sample code.
I'll be appreciated your help in this regard.
Please check the o/p of this program.

#include <iostream.h>
#include <iomanip.h>

int linearSearch(int array[], int key, int sizeOfArray)

for(int n=0; n < sizeOfArray; n++)
if(array[n] == key)

int get_size()

cout << "Enter the size of the array " << endl;
cin >> size;
return size;
}

//main function declaration
int main()

cin >> choice;

switch (choice)

//checking choice bounding

well what do you want exactly?...
to learn how to use templates
or to have this program in c++ style

do you have msdn
look up 'vector' and 'CArray'

This looks like homework to me

Mmm yes to me too... And many people think that we would provide them with full working functional programs just because of their 'good looks' or whatever
