hi
how can I do this condition between client and server

in data.txt I have these username

11
22

in server.c
I write this before main

typedef struct
{
   int    name;
}client;
client inputQ[30];

then I receive username from client
now I want check if this username in data.txt file or not
my question is
how can I check that username in data.txt file or not

if(strcmp(buffer,inputQ[i].name)!=0)
			{
				printf("you are here");
			}
			else
			printf("you are not here");

buffer is what I received from the client

and I got this warning

warning: passing argument 2 of 'strcmp' makes pointer from integer without a cast

Solution 1

You did not show the definition of buffer but I assuming it is an array of char or a char *. In either event, your name field of the struct is an int. You cannot use strcmp() to compare these two dissimilar types.

Either store the data from your file as chars or convert the incoming buffer contents to an int. Your choice.

int p = atoi(buffer);
if (p == inputQ[i].name)
