一个c++括号匹配程序

以下是我写的一个括号匹配程序，现在要加入两个功能：一，将输入的的字符能够输出来；二，将c++的注释和字符串并入括号匹配程序，忽略掉注释或字符串内的任何括号；
不知怎么才能够实现，希望能够帮助以下，谢谢了！！！

#include<iostream>
#include<stack>
using namespace std;
int main()
{
stack <char> openings;
stack<char>temp1;
char x;
stack<char>temp2;
char symbol;
bool is_matched = true;

while ((symbol = cin.get()) !=cin.eof()) {

if (symbol == '{' || symbol == '(' || symbol == '[')

openings.push(symbol);
if (symbol == '}' || symbol == ')' || symbol == ']') {

if (openings.empty()) {
cout<<endl << "Unmatched closing bracket " <<" <"<<symbol<<">"
<< " detected." << endl;
is_matched = false;
}

else {

char match;
match=openings.top();
openings.pop();

is_matched = (symbol == '}' && match == '{')
|| (symbol == ')' && match == '(')
|| (symbol == ']' && match == '[');
if (!is_matched)
cout<<endl << "Bad match"<<match<<symbol<<endl;

}

}

}
if (!openings.empty())
cout << "Unmatched opening bracket(s) detected." << endl;

return 0;

}

这个用栈实现很容易的，要的话就给你发个，用C实现的
