this is what I have so far
#include <iostream>
#include <string>
#include "aStack.h"
#include "AQueue.h"
using namespace std;
bool match(char, char);
bool isValid(char);
int main(){
char ch;
char chL, chR;
aStack S;
AQueue A;
int count = 0;
bool err = false;
while((ch=cin.get())!= EOF){
cout << ch; //Echo back data
if(ch!= '\n')
{
if(!isValid(ch))
{
ch = "";
S.push(ch);
A.Enqueue(ch);
}
else
{
S.push(ch);
A.Enqueue(ch);
count++;
}
}
while(count > 0)
{
S.pop(chL);
A.Dequeue(chR);
count--;
if(!match(chL, chR))
err = true;
}
if(err == true)
cout << "Not a valid pack palindrome." << endl;
else
{
cout << "Palindrome is valid" << endl;
err = false;
}
}
return 0;
}
bool match(char chL, char chR){
if(chL == chR)
return true;
else
return false;
}
bool isValid(char ch){
if((ch>= 'a' && ch <= 'z') || (ch >= 'A' && ch <= 'Z'))
return true;
else
return false;
}
My problem comes when I try to get rid of the punctuation. I get this
error:
project3.cpp:29: error: invalid conversion from 'const char*' to
'char'
If someone could help me I would greatly appreciate it.
