How do I fix error "use of undeclared identifier n" in C? -


I'm sure there are probably many syntax / other errors, but I'm trying to figure out that it's on I am very new to this, so I really do not know how to fix the undisclosed identifier. Note that #include & lt; Cs50.h & gt; is the only CS50 library 

  #include & lt; Cs50.h & gt; # Include & lt; Stdio.h & gt; Int main (zero) {int sum, fee, disc; Printf ("For rates with tax and security deposits, type 10 percent, type n:"); String name = GetString (); If (name == y) {printf ("pretext amount:"); scanf ("% d", and fee); printf ("Well, I'll add 10% tax to% d. \ n", fee); Add = (1.1 * fee); printf ("plus tax amount =% d \ n", add); Printf ("Security deposit = 1000 dollars \ n"); Printf ("Total = (% D + 1000)", add); } And if (name == n) {printf ("pretext amount:"); Scanf ("% d% d", & amp; fee, & amp; disk); printf ("OK, I'll add 10% discount to% d and then add tax. \ n", fee); Add = (0.9 * fee); Disk = (add * 1.1); printf ("discount rebate amount plus tax =% d \ n", disc); Printf ("Security deposit = 1000 dollars \ n"); Printf ("Total = (% D + 1000)", disk); } Return 0; }   
 Errors:  
  contractable helper.c: 10: 17: error: unauthorized identifier 'Y' if used (name == y) ^ ContractualHelper .C: 22: 22: Error: If the use of undisclosed identifier 'N' (name == N) ^ 2 errors generated.    
 
 
  y  and  n  Because they do not give definition.  
  int y;  is an announcement, which will get rid of that error.  
 However, your code is  
  if (name == y)   
 one variable  name  Comparing a variable  y , and I think what you want to do is that if  name  is in the string  y  .  
 This comparison is another problem.

c# - ASP.NET MVC - Attaching an entity of type 'MODELNAME' failed because another entity of the same type already has the same primary key value -

In brief, the wrapper module is inserted during posting and the status of an entry is changed to 'modified' . Before changing the state, the state is set to 'separate', but calling attachments () causes the same error to be thrown away. I am using EF 6.
