AP CSP Unit 7: Parameters, Returns, and Libraries

Front

Which code segment results in "true" being returned if a number is even? Replace "MISSING CONDITION" with the correct code segment.
function isEven(num){
if(MISSING CONDITION){
return true;
} else {
return false;
}
}

Back

num % 2 == 0;

Front

Which function calls would provide the most helpful test of this function? Remember: With tests, you are attempting to figure out all the possible ways the function could be broken. function findMin(num1, num2){ if(num1 < num2){ return num1; } else { return num2; }}

Back

findMin(-1,1), findMin(1,-1), findMin(1,1)

Front

listAverage() returns the average number in a list. Which of these functions does this correctly?

Back

Front

What is printed to the console?
console.log(15 % 4);

Back

3

Front

Which of the following is NOT true about procedural abstraction?
Procedural abstraction improves code readability,
Procedural abstraction manages complexity by allowing for code reuse,
Procedural abstraction improves the speed at which a program executes,
Procedural abstraction allows a solution to a large problem to be based on the solution of smaller subproblems.

Back

Procedural abstraction improves the speed at which a program executes.

Front

This function finds the minimum number in a list. What should <MISSING CODE SEGMENT> be replaced with in order for this function to operate as expected?
function min(numList){
var min = numList[0];
for(var i=0; i<numList.length; i++){
if(numList[i] < min){
<MISSING CODE SEGMENT>
}
}
return min;
}

Back

min = numList[i];

Front

Algorithms can be created in all the following ways EXCEPT: creating from an idea, combining existing algorithms, removing sequencing, selection, and iteration from an algorithm, modifying existing algorithms

Back

removing sequencing, selection, and iteration from an algorithm

Front

Using existing algorithms as building blocks for new algorithms has all the following benefits EXCEPT: reduces development time, reduces testing, simplifies debugging, removes procedural abstraction

Back

removes procedural abstraction

Front

What is one of the benefits of using a library in a program?

Back

simplifies creating a complex program

Front

Which call of the function correctly follows the instructions laid out in the API? Options: moveElement("button1", 2, 23); moveElement("button1", "left", "thirty"); moveElement("button1", 30, "two"); moveElement("button1", "down", 25);

Back

moveElement("button1", "down", 25);
