executing code in a String!

[v4vijayakumar]

How i can execute c++ code in a String?

for example,
string code = "cout << \"hi\" << endl;";
execute(code);

How i can implement that "execute(std::string code)" function?

There's no such functionality provided by the language or its standard
library.

But you could a C++ interpreter, provided it has some 'eval' hook.

Google for that (or, as I recall Wikipedia had an informative page).

// Just to give an idea:

void execute(std::string str)
{
std:fstream o("temp.cpp");
o << "#include <everything.hpp>"
<< "int main(){" << str << "}";

o.close();

system("g++ temp.cpp");
system("a.out");
}
