Client Server Programming

Here the code executes the required output perfectly
It checks for the condition and prints the error if the condition is not true , but it also prints even if the condition is true and followed but the required output.
finding problem in a small if else condition
how it can corrected

In the below codeif (fork() == 0) & if (!request.compare("") == 0) has no effect

/* Loop forever */ 
while (1) 
{
/* Accept a client connection */    
    clientFd = accept (serverFd, clientSockAddrPtr, (socklen_t*)&clientLen); 

//Fork child
    //if (fork() == 0) 
    {
    while(1)
    {   //Reads the client
            string request = read_Request (clientFd); 
        bool found = false;
        string response="Error !!! Country not found"; 
        //if (!request.compare("") == 0) 
        {

            for(vector<Country>::iterator it = countryData.begin(); it != countryData.end(); it++)
            {
        if(request.compare(it -> name) == 0) 
        {   
        string countryName = it -> name; 
        response += "\n";               
        response += it -> name; 
        response += "'s TLD Code"; 
        response += ((countryName).append("'s TLD Code")); 
        response += ": ";
        response += it -> TLDCode; 
        response += "\n";

        countryName = it -> name;
        response += it -> name;
        response += "'s FIPS104 Country Code"; 
        response += ((countryName).append("'s FIPS104 Country Code")); 
        response += ": ";
        response += it -> FIPS104CountryCode; 
        response += "\n";

        countryName = it -> name;
        response += it -> name;
        response += "'s ISO2 Country Code"; 
        response += ((countryName).append("'s ISO2 Country Code")); 
        response += ": ";
        response += it -> ISO2CountryCode; 
        response += "\n";

        countryName = it -> name; 
        response += it -> name; 
        response += "'s population"; 
        response += ((countryName).append("'s population")); 
        response += ": ";
        response += it -> population; 
        response += "\n";


            found = true;

            }
        }
}



write (clientFd, response.c_str(), strlen (response.c_str()) + 1);  
    }
    }

        close (clientFd); 
}

}

Here is the snip of output

The string response is printed in case of both true and false.

Any suggestions please

Solution

Okay so here you assign a string to the variable response
String response="Error !!! Country not found";

then here you concatinate other string to response, which gives you your output.

response += "\n";               
response += it -> name;

i.e. Error !!! Country not found + \n + it->name etc

Secondly as @ChrisJ.Kiick said you have a mysterious String type which isnt a part of the c language
