{
for(int j=0;j<Sub[i].size();j++)
{
SF.push_back(Sub[i][j]); //SF final subset of string input....
}
}
}The above is the code for generating subsets of a given string.Global declarations are
vector<vector<string> > Sub;
vector<string> SF;
The code works properly and I am able to get the subsets in SF.But I am not able to access individual characters in string.Is it not possible? And is there a way to change the string to 'char*'? Not const char* because I need to use it on the program.
Thanks in advance.
