use ispunct to remove the punctions from the string then print the new string

use ispunct to remove the punction in a string then print that string without punctions

#include <iostream>
#include <conio.h>
#include <cctype>
#include <string>

using namespace std;

int main()
{
cout <<"Enter a complete Sentence" <<endl;
string Sentence;
getline(cin, Sentence);

string punction;
for(string::size_type index=0; index < Sentence.size(); index++)
{
if(ispunct(Sentence[index]))
{
punction=ispunct(Sentence[index]);

}else{cout <<"failed" <<endl;}

}
cout << punction <<endl;

getch();
return 0;
}

my output is a right sided triangle. this is error. whats wrong?

if(ispunct(Sentence[index]))
   punction=ispunct(Sentence[index]);

if Sentence[index] is a punctuation mark then set punction to the fact that Sentence[index] is a punctuation mark

Bazzy just paraphrased what your code actually does.
