Please help my code won't work
`Hey,
Note: If you have any queries related the answer please do comment. I would be very happy to resolve all your queries.
Please note there were many syntax errors I have changed char array to string since substr works for string
#include<iostream>
#include<cstring>
using namespace std;
string reg;
int main()
{
//char reg[30];
int flag = 0;
int n, ni, i, j, k;
cout << "Enter a regular expression: ";
cin >> reg;
cout << endl;
n = reg.length();
for (int i = 0; i < n; i++)
{ string DNA;
string temp=reg.substr(i, j);
DNA=temp;
ni =DNA.length();
for (k = 0; k < ni; k++)
{
if (DNA[i] == 'A')
flag = flag + 1;
}
if (flag >= 2)
cout << DNA<<endl;
}
return 0;
}
Kindly revert for any queries
Thanks.
