Will any body help me with C++?

Ok so i i had a program made a while back that i used at my school to basically get around the fire wall kinda. Our school blocks us to use .exe files so i made a program that allowed me to type in the directory of the file that i wanted to boot and it would boot it.

Its been awhile since ive used C++ and i dont exactly remember how to do every thing so im trying to remember how to remake this program. any help would be apreciated

This is what i have so far

#include <iostream>
using namespace std;
int main()
{
int d;
cout <<"Enter the Directory of the file you would like to open";
cin >>d;
system //i no some thing goes here and this is what actualy boots it but not really sure how its written
return 0;
}

it's called "executing", "booting" is when you turn your computer on.
This code should work-


#include <iostream>
#include <cstdlib>
using namespace std;

int main()
{
string programName;
cout <<"Enter the Directory of the file you would like to open";
cin >>programName;
std::system(programName.c_str());

return 0;
}
