C++ abrir programa somente por execultavel externo usando

[JULIOLIMAPILOTO]

tenho um programa que so abre dessa forma
 

for(int i=1;i<argc;++i) {
		if (target_option_compare(argv[i], "senha-xxxxxxxxxxx")) {
			opt_cfg = argv[i+1];
			++i;

assim meu programa em c++ é so abre a partir de outro execultavel inserindo esta senha 
quero fazer a mesma coisa com outro programa 


 

int main(int argc, char *argv[])
{
	
//-------------------------------------------------	
	//codigo seria aqui 
	
	
	
	
	
//--------------------------------------------------	
	std::string config_path, cmdln_font, log_file;
	bool launch_game = false;
	bool process_console = false;
	FeLogLevel log_level = FeLog_Info;
    char PegaFicha[100]; //julio
	char PegaBloqueado[100];//julio
	int RetFicha; //julio
	process_args( argc, argv, config_path, cmdln_font, process_console, log_file, log_level );

	FeSettings feSettings( config_path, cmdln_font );
    
	//
	// Setup logging
	//
#if defined(SFML_SYSTEM_WINDOWS) && !defined(WINDOWS_CONSOLE)
	if ( log_file.empty() ) // on windows non-console version, write log to "last_run.log" by default
	{
		log_file = feSettings.get_config_dir();
		log_file += "last_run.log";
	}
#endif
	//
	// If a log file was supplied at the command line, write to that log file
	// If no file is supplied, logging is to stdout
	//
	if ( !log_file.empty() )
		fe_set_log_file( clean_path( log_file ) );

	// The following call also initializes the log callback for ffmpeg and gameswf
	//
	fe_set_log_level( log_level );

	//
	// Run the front-end

nao estou conseguindo formular este codigo
