output empty

[tefa2014]

i did a binarysearch usig c++ but the output is empty

  
#include<iostream>
using namespace std;
int binarysearch(int a[],int maxsize,int target)
{
	int low=0;
	int high=maxsize-1;
	int mid=(low+high)/2;
		while(a[mid]!=target && low<=high)
		{
			if(a[mid]>target)
			{
				high=mid-1;
			}
			else
			{
				low=mid+1;
			}
		}
		if(a[mid]==target)
		{
			return mid;
		}
		else
		{
		return -1;
		}
}
int main()
{
	int j[8]={1,2,3,4,5,6,7,8};
		binarysearch(j,8,5);
}

You should probably be changing mid in your while() loop instead of high and low. And you should probably use the return value instead of discarding it in main().

[tefa2014]

can you write the code pleasse

No, thank you anyway. You give it a try.
