    strcat it to a buffer, system( buffer ).

    Hope is the first step on the road to disappointment.

    You need to try first, or at least give us a clue as to what direction we're going.

    Are you working with C++ strings or C strings (char arrays) ? I guess I'll have to explain with an example:

    Code:
    // C style string
    char ipaddress[30];
    std::cin >>ipaddress;
    
    // C++ style string
    std::string ipaddress;
    std::cin >>ipaddress;
    Which are you using?
    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]
