Searching an 2d array using pointers

[touches]

I am using an 2d array to search for the key 32 using pointers.. Now whenever i try to compile i get an linker error saying undefined symbol find_key(int *far,int,int)..
I know the error is with the use of pointers and the way i am passing them... Can anyone help me out

#include<stdio.h>
#include<conio.h>
#include<stdlib.h>
#define N 4
void find_key(int *,int,int);

void main(){
	clrscr();
	srand((unsigned)time(NULL));

	int arr[N][N];
	int *p;
        int key=32;
        int len=16;
	int count=0;
	for(p=&arr[0][0];p<=&arr[N-1][N-1];p++){
		if(count==4){
			*p=32;
		}
		else{
		*p=rand()%10+1;
	}
		count++;
	}
	for(p=&arr[0][0];p<=&arr[N-1][N-1];p++)
		printf("\n%d",*p);

	find_key(&arr[0][0],len,key);
	getch();
}
void find_temp(int *a,int n,int k){
	int *p;
	for(p=a;p<a+n;p++){
		if(*p==k)
			printf("\nfound key at %d",p);
		else
			printf("\nnot foumd");
	}
}

Look at your line 31

void find_temp(int *a,int n,int k){

Change the function name to 'find_key', cause that's what you declared above 'main'.

void find_key(int *a,int n,int k){

See if that works...

@ashitpro
Oh yeah it works sorry silly me... i didnt check with the function names..
anyways i'll experiment with different pointer notations of passing an argument.. and if i'm stuck i'll post it here

anyways thanks a lot

Now in the above code if i want to process only the rows.. this code works fine.. if i want to send each row one by one to the function to find the key can i pass the first array element arr[0] like find_key(arr[i],len,key) in the function call?? how would i write a function prototype for that?? I want to send each row of the 2d array one by one to the function to find the key
I am really stuck as i could not understand parameter passing of pointers in 2d arrays to functions?? Can anyone explain that concept please??

for(p=arr[i];p<=arr[i]+N;p++){
        printf("\n%d",*p);

The way you are current declaring and calling find_key is not, in my opinion, a good design.
