c - system() output to a char* -

  int system (const char *)   
 How can I send output I can order this command (say that the command is "pwd") in four * Its return is an integer but I want the result of the command to be sent in four *.   
 
 
 You can use the command "pwd" in the form of "tempfile" directly to the output of the command pipe Can do. 
 Another method is to use  popen   
 FILE * output = popen ("PWD", "R");  
 This will give you a file indicator where you can read the output.
