c - 2nd Call to strtok() returns null -


I am at the top of the loop in client file for client / server communication. I get user input (input) from client And I need to straddle in CMD and CMD 2 for the work of my IFS.

The user is said to be "find friend" (this is a good command for the program). Using the following code, CMD = "meet" (yay!), But CMD 2 = "(empty)"

input is a four input [30] CMD and CMD 2 letters start in four letters Are there.

A little help here? Thanks! / * As long as the user exits from the program / (Cmdnum! = 7) {printf ("\ nPlease enter a command:"); Scanf ("% 30s", input); CMD = Strontok (Input, ""); Printf ("CMD:% s \ n", CMD); If (SRCMP (CMD, "mill") == 0} {cmi2 = strotok (zero, "\ 0"); Printf ("cmd2:% s \ n", CMD2); Pstatus = Print (CMD, Sokfad); If (pstatus == 1) {printf ("printing print \ n"); }} And if (strcmp (cmd, "put") == 0) ..... etc, etc. ....

"\ 0" Think about it, it's just an empty string.

More importantly, you need to read in the entire line, which is scanf with % s Do not do this. It closes in the first place instead, try fgets But remember that it leaves the new line, so add it as a limit. #include int main () {four input [50]; printf ("Please enter an order Fgets (input, size input, stdin); four * CMD = string (input, "\ t \ n"); Printf ("CMD: [% s] \ n", CMD); SRCMP (CMD, "Receive") == 0} {char * cmd2 = strtok (NULL, "\ t \ n"); printf ("CMD 2: [% s] \ n", CMD2);} Return 0;}

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
