class template

[akashvij]

hello everybody
This is my first time here. I am working on a class project on class template. i have to give member function definition. Plz help me i am not able to understand what i am suppose to do. Plz give me some hints or explanation about it.Member function is

bool readFromFile(char *fileName)-> read data of type t from the file named 'filename',and store the data into the array.Returns true if reading was successful,false otherwise.
and i have one more member function
bool printIntoFile(char *fileName)->dump the contents of the array into a file named 'filename'.Return true if writing was succesful, false otherwise.

I've given you the structure of a template class... It's up to you to code the reading and the writing.

hint:
while redaing or writing... remember that you don't know the type of data... you should use TYPE when declaring variables...

examples:
int i; //bad
cin >> i;

TYPE i; //good
cin >> i;

/---------------------------------------------/

// Main.cpp
#include "Container.h"

void main(){
Container<int> ctnr;
ctnr.readFromFile(&quot;in.txt&quot;
ctnr.printIntoFile(&quot;out.txt&quot;
}

/---------------------------------------------/

// Container.h
#ifndef _Container_h_
#define _Container_h_

template <class TYPE>
class Container{
protected:
TYPE arr[1024]; // choose an appropriate number.
public:
bool readFromFile(char *fileName);
bool printIntoFile(char *fileName);
};

#include &quot;Container.cpp&quot;

#endif

/---------------------------------------------/

// Container.cpp
#ifndef _Container_cpp_
#define _Container_cpp_

#include &quot;Container.h&quot;

template <class TYPE>
bool Container<TYPE>::readFromFile(char *fileName){
bool returnValue=true;
// your code to read the file
return returnValue;
}

template <class TYPE>
bool Container<TYPE>:rintIntoFile(char *fileName){
bool returnValue=true;
// your code to write the file
return returnValue;
}

#endif
