	for(i = 0; i < N; i++)

	std::cout << "Enter the data to be serched : \n";

	std::cin >> data;

	intial 0;
	final = N - 1;
	mid = (intial + final)/2;

	while((intial <= final) && (A[mid] != data))
	{

		else
			intial = mid + 1;
	}
	if (A[mid] == data)
		std::cout << "Data Present \n";
	else

please help me where i am wrong

the error is telling you to look at line 19,

although the error message isn't very helpful, you should still be able to see that it should read "initial = 0;"

@Jaybob66

Thanks problem solved....
it was just initial = 0;

however there is another problem
i entered 10 ascending number : 1 2 3 4 5 6 7 8 9 10

now if i enter number to be searched = 5
then it will show present status

however if i will search 12(which is obviously not there)
it(Console) just keeps on blinking and i have to terminate it with Ctr + c
and win task manager shows CPU USAGE = 100%
as soon as i terminate it gets down too
whats the problem
