Question

I have problems with inserting string variable inside text.

string p="http://www.google.com" ;
system("c:\\progra~1\\intern~1\\iexplore.exe \"http://www.google.com\"");

I need a way to use p instead of “http://www.google.com\”
I tried

  system("c:\\progra~1\\intern~1\\iexplore.exe \%p\"");

but it doesn’t work. I’m not very good with strings so probably that’s the prob.

In C++ you can use the + operator to concatenate strings:

system((std::string("c:\\progra~1\\intern~1\\iexplore.exe ") + p).data());

In this case this is a bit hard to read, so you’re better off creating the string before hand.
A better way would be to use stringstream:

#include <sstream>

std::stringstream sstr;
std::string p = "http://www.google.com";
sstr << "c:\\progra~1\\intern~1\\iexplore.exe " << p;
system(sstr.str().data());
