Sure, tell me the e-mail of your professor at school and I'll ask him to give you a break.

Are you this moronic by birth or do you practice day by day?
Don't you remember when your teacher told you that cheating was not good for you?

We don't give school assignment solutions. You would have known that, if you took the time to read the rules of this forum.

The premise behind this forum is this; to help people that help themselves.
I doubt you make the cut. However, you will always be "encouraged" to show your efforts and to make explicit where you are having troubles with.

No! Not at all.
int i,j, surname[N],name[N],ID[N],grade[M][N]; Tell me! What type should be the memory that will hold a name or surname? And grade?

scanf("%s",name,surname,id) Three type of variables, but I only see one "%s" format operator.

scanf("%s",grade[i][j]); At best, grade[i][j] would be a single char or int, which can not receive a formatted "%s".

(*rats I wasn't first reply *)

int i,j surname[N],name[N],ID[N],grade[M][N]; Declares all of those variables as integer. Should some of them have character data?

The format in scanf("%s",name,surname,id) will only read one string value. surname and id will be empty. (But as noted above, name, surname and id are all integers anyway.)

This for statement:
c Syntax (Toggle Plain Text) 
  1. for (j=0; j<=M; j++)
  2. printf("give grade for the %d lesson,j+1);
  3.  
does not have any braces on it and so will loop only the first statement.

You don't have enough matching braces yet, could you try to compile it and post code that compiles?

and when posting c code, please use c code tags
[code=c]
/* Your code here */
[/code]
