statements

I am writing a simple program for a homework problem and It seems to be skipping my if statement. I have looked at other questions posed, and the problems there do not seem to be my problem so I am hoping you can help. def isWordGuessed(secretWord, lettersGuessed): if lettersGuessed == []: return False else: for i in lettersGuessed: if i in secretWord == False: return False else: if i == lettersGuessed[-1]: return True When I place in some print functions to see what it is doing, it completely skips if i in secretWord == False: I have placed right above this line print i in secretWord and it

I don't know what's missing or why it isn't displaying data. My code is working if I'm not using prepared statements. When I used prepared statements, it seems that code is not working anymore. db.php Class Database{ public $mysqli; public function __construct($db_host, $db_user, $db_password, $db_name){ $this->con = new mysqli($db_host, $db_user, $db_password, $db_name); } public function selectUserInfo($id){ $stmt = $this->con->prepare("SELECT * FROM users WHERE os_id = ?"); $stmt->bind_param("s", $id); if($stmt->execute() == FALSE){ trigger_error($stmt->error, E_USER_ERROR); }else{ $data =

Just wondering if anyone can help with this, I have two PLSQL statements for altering tables (adding extra fields) and they are as follows: -- Make GC_NAB field for Next Action By Dropdown begin if 'VARCHAR2' = 'NUMBER' and length('VARCHAR2')>0 and length('')>0 then execute immediate 'alter table "SERVICEMAIL6"."ETD_GUESTCARE" add(GC_NAB VARCHAR2(10, ))'; elsif ('VARCHAR2' = 'NUMBER' and length('VARCHAR2')>0 and length('')=0) or 'VARCHAR2' = 'VARCHAR2' then execute immediate 'alter table "SERVICEMAIL6"."ETD_GUESTCARE" add(GC_NAB VARCHAR2(10))'; else execute immediate 'alter table "SERVICEMAIL6

If you have an if-statement in C# that checks multiple conditions: if (a == 5 && b == 9) { ... } Does b == 9 still get checked if a == 5 condition is false, or does it automatically exit since there's no way this could pass anymore? Similarly, for an OR if-statement: if (a == 5 || b == 9) { ... } Will b == 9 still get checked if a == 5 is true? Both && and || is "short-circuiting" operators, which means that if the answer is known from the left operand, the right operand is not evaluated. This means that: a && b b will not be evaluated if a is false, since the final answer is already known.
