hey i tried to make a program to find an item in an integer array using binary search technique n by iteration with the help of functions...but i am getting errors....so plz help me out..

Please post your code and the errors.

If you don't show that you have actually tried by posting your code, no one in this community is going to help you. We can't debug your program and help you with errors if you don't show us what to help you with.

EDIT:
Looks like Tom Gunn is one step ahead of me, as always! :)

hey m a new user....n i tried to make a program to search a no. in an integer array using binary search tech,,,,n w/o recursion but the program i made is not doing well....
the position of the no. to b searched is cuming out to b wrong with a null pointer assignment....
here's the program i made...i tried to hard but still there's the same problem...so plz lemme knw where m i going wrong with this program....
here's my program....

/*A PROGRAM TO SEARCH AN ELEMENT IN 1D ARRAY USING BINARY SEARCH USING ITERATION*/
#include<stdio.h>
#include<conio.h>
void binary(int array[],int n,int ele)
{
    int beg=0;
    int end=n-1;
    int mid;
    mid=(beg+end)/2;
    while((beg<=end)&&(array[mid]!=ele))
    {
        if(ele>array[mid])
        beg=mid+1;
        else
        end=mid-1;
        mid=(beg+end)/2;
    }
    if(array[mid]==ele)
    printf("element found at %d",mid);
    else
    printf("element not found\n");
}
void main()
{
    int array[50],i,ele,n;
    clrscr();
    printf("the list should be sorted in ascending order\n");
    printf("enter the size of array\n");
    scanf("%d",&n);
    printf("enter the elements\n");
    for(i=0;i<n;i++)
    {
        scanf("%d",array[i]);
    }
    printf("enter the element to be searched\n");
    scanf("%d",&ele);
    binary(array,n,ele);
}

thanx

Your program is pretty close, you just need a few changes, such as int main() , use pointer to array in scanf() and flush out the '\n' characters

int main()
{
	int array[50],i,ele,n;
    char a;
	//clrscr();
	printf("the list should be sorted in ascending order\n");
	printf("enter the size of array\n");
	scanf("%d%c",&n,&a);
	printf("enter the elements\n");
	for(i=0;i<n;i++)
	{
		scanf("%d%c",&array[i],&a);
	}
	printf("enter the element to be searched\n");
	scanf("%d%c",&ele,&a);
	binary(array,n,ele);
}

hey thank you ancient dragon....it worked....but will u plz lemme knw...how this char a made the program to be correct....wats its effect on the program...????

<snipped> Nevermind that was a bad post, sorry.
