I am having a problem to call a function
I am posting the code...
Can anyone help how we can solve the problem...

int AES(string path1, string path2)
        ifstream myfile1 (path1, ios::binary);// error
	ofstream myfile3  (path2, ios::binary);//error

int main()
    AES( "c:/plaintext.txt" , "c:/cipheretxt.txt" );
    return 0;

The filename parameter has to be a C-style string:

ifstream myfile1 (path1.c_str(), ios::binary);
ofstream myfile3  (path2.c_str(), ios::binary);
commented: Very Helpful +1

fstream parameters require const char*, not string. So pass the c_str() method ifstream myfile1 (path1.c_str(), ios::binary) [edit]^^^ what Narue said.[/edit]
