Programming Quiz Time #5 !

[raider00321]

ok. So waht will this quiz be of.... hmm... another trace question?? nahh. hmm another find the errors?? nahh... How about... a 5 question a qustionaire!! ok i like... person whpo gets most or all of the questions right wins...
(worth 1 point each)
1. Where are the x and y co-ordinates 0,0 on the root Stage?
2. How do you define the height and width of an object using script?
3. What is a case statement and what is the code needed for one to work?
4. What is the difference between a for and while loop?
5. What code is used to check collisions between certain objects?

BONUS QUESTION
what is the difference between == and ===?(worth 3 points)

The last question is worth so much because its actually somthing many programmers dont know

1. top left
2. this._height = #
this._width = #
3. no idea
4. a for loop runs a set number of iterations (usually) whereas a while loop continues until its conditions are met.
5. hitTest

Bonus: (this is a complete guess but...) == is used for checking if values are equal and === is for checking if arrays are equal

well i don't know even the programing basics XD

i guess secondLaw wins again lol
so for the answers too al the questions...

1. top left
2. this._height = #
this._width = #
3. a case statement is similar to a if and else statement except can only check for exact values. Another name for a case statement is a switch statement. Ill use an example out of flash help..
var thisMonth:Number = new Date().getMonth();
switch (thisMonth) {
 case 0 :
 trace("January");
 break;
 case 1 :
 trace("February");
 break;
 case 5 :
 case 6 :
 case 7 :
 trace("Some summer month");
 break;
 case 8 :
 trace("September");
 break;
 default :
 trace("some other month");
}


4. a for loop runs a set number of iterations (usually) whereas a while loop continues until its conditions are met.
5. hitTest

Bonus:  == is used for checking if values are equal and === is for checking that the variable, object, instance is exactly the same comparing even the type is is. e.g a sting or an int or a boolean. Usually best used when comparing strings in flash .

[Turn-Coat]

1. Top Left Corner
2. _width and _height found in the MovieClip Class
3. Used in a Switch, which is a simplified multiple if...then statement. Switch(expression or variable){
case "number or letter": put code here;break;
}
4. a for loop can perform hundreds of iterations for a variable in just seconds. A while loop evaluates whether or not a condition is true.
5. hittest, but you can also check using x and y coordinates.

BONUS QUESTION
This one is crazy, but logical. == stands for "is equal" so if I said a=2+3 and b=5, I could say a=b. === stands for "grammar nazi", a does not equal b, because flash is too stupid to realize that 2+3 is 5. But if I said a=6 and b=6, it
would totally be down for that.
