Well I do it like this:

Code:
char choose[1];
	do {
		
			
			cout << "New check? Y/N \n";
			cin >> choose;
			if (_stricmp("N", choose) == 0)
			{
				break;
			}
			char name_for_check[10];
			cout << "\n Name for check:";
			cin >> name_for_check;

			for (i = 0; i < n; i++)
			{
				if (strcmp(array[i].first_name, name_for_check) == 0)
				{
					cout << array[i].first_name << " ";
					cout << array[i].last_name << " ";
					cout << array[i].country << endl;
				}
			}


	

	}
	while (_stricmp("Y", choose) == 0);
	system("pause");
}
The code is working but after I run it it show this message:
Run-Time Check Failure #2 - Stack around the variable 'choose' was corrupted.
