Having a string within a system()

Question

How can I use a string within a system(). ex: (input is the string)

system(\"open -a Google Chrome\" \"http://www.dictionary.reference.com/browse/\" + input + \"         


        

Answer 1

Have you included the stdlib header?

No matching function for call to 'system' typically occurs when it cannot resolve a function with that signature.

EG:

#include  // Needed for system().

int main()
{
    system("some argument"); 
    return 1;
}

And don't forget to .c_str() your std::string variable when passing it in as an argument.
