Defined in header <cstdlib>
int system( const char *command );

Calls the host environment's command processor with command parameter. Returns implementation-defined value (usually the value that the invoked program returns).

If command is NULL pointer, checks if host environment has a command processor and returns nonzero value only if it the command processor exists.

Parameters

command

-

character string identifying the command to be run in the command processor. If NULL pointer is given, command processor is checked for existence

Return value

Implementation-defined value. If command is NULL returns nonzero value only if command processor exists.
