QuestionConverting different data types from a class template. Pin
Member 382253227-Nov-09 15:10
Member 382253227-Nov-09 15:10 
I'm wondering if there is a simple/efficient process to which i can convert from a template class to any other primitive/abstract data type.


I'll give the coding snippets that pertains to the problem I'm having..


DRIVER PROGRAM--just show what it does globally...

<br />
int main()<br />
{<br />
<br />
char cCatchVar;<br />
float fCatchVar;<br />
int iCatchVar;<br />
sExample sCatchVar;<br />
<br />
<br />
<br />
<br />
Stack<char> ocStack1(4);<br />
Stack<int> oiStack1(4);<br />
Stack<int> oiStack2(4);<br />
Stack<float> ofStack1(4);<br />
Stack<float> ofStack2(4);<br />
Stack<sExample> osStack1(4);<br />
<br />
<br />
<br />
<br />
cout << "\n pushing value ')' in template class char...";<br />
ocStack1.push(')');<br />
<br />
<br />
cout << "\n pushing value 2 in template class int...";<br />
oiStack1.push(2);<br />
<br />
cout << "\n pushing value 12 in second template class int \n (to demostrate the != operator)... \n \n";<br />
oiStack2.push(12);<br />
<br />

and so on for the pushing and popping of the stack...





I need to be able to enforce balanced parenthesis format for whatever data types happen to be in the stack.
The way i figure is that there must be someway to be able to to recognize what data type is being used with the class template at runtime, distinguish it, and continue with the checking of the balanced parenthesis.



this is how the push function of the stack uses my incomplete balanced parenthesis class function..


<br />
template <class T><br />
void Stack<T> ::push(T c)<br />
{<br />
	<br />
bool bError=false;<br />
<br />
//bError = checkParen();// THIS IS THE FUNCTION<br />
	<br />
//if(bError)<br />
//{<br />
	//cout<<endl<<"ERROR--input needs balanced parenthesis \n ;<br />
//}<br />
<br />
 if (isFull())<br />
{<br />
	cout << "The stack is full. \n";<br />
}<br />
else<br />
{<br />
	iTop++;<br />
	cStackArray[iTop] = c;<br />
<br />
}<br />
}<br />
<br />
<br />



this is the actual coding of my attempt for the function.....
<br />
<br />
template <class T><br />
bool Stack<T> ::checkParen()<br />
{<br />
<br />
T cCatchPop;<br />
bool bStatus1 = false;<br />
bool bStatus2 = false;<br />
bool bStatus3 = false;<br />
char cLeftPar = '(';<br />
<br />
<br />
//char cRightPar = ')';<br />
<br />
Stack::iCharsInStack++;<br />
Stack::pop(cCatchPop);<br />
<br />
Stack::push(cCatchPop);<br />
if(iCharsInStack==1)<br />
{ <br />
bStatus1 = false;<br />
}<br />
else<br />
{<br />
bStatus1 = true;<br />
}<br />
if(bStatus1 == true || bStatus2 == true)<br />
{<br />
bStatus3=true;<br />
}<br />
<br />
return bStatus3;<br />
<br />
<br />

the coding above for the checkparen function is incomplete and has been deleted through, revised, completely deleted,changed around about 4 times and probably doesn't represent my best attempt at the problem. I just thought posting the code might be helpful to explain my problem anyway.
Basically i tried everything I thought would work. So any advice would be helpful.

Thank you in advance!!
