Right. That then presents a template chooser where you can choose from a variety of templates. Which did you choose?

Oh, but wait, earlier you mentioned C++. Are you trying to run C++ code in a playground? That’s going to… challenging. Playgrounds only support Swift.

NOTE!!

************this program in Dev-C++ is compile but in Xcode don't run*********

#include <iostream>

using namespace std;

int binary_search (double arr[], int N, double target) {

int first = 0, last = N - 1, mid;

while (first <= last) {

mid = (first + last) / 2;

if (arr[mid] == target)

return mid;

else if (target < arr[mid])

last = mid - 1;

first = mid + 1; }

return -1;}

int main() {

int N;

cin >> N;

double numbers[N], item;

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

cin >> numbers[i];

cin >> item;

cout << binary_search (numbers, N, item) << endl;

return 0; }
