C++ Jeopardy Midterm Review

That's so fetch

100

This common operator is used with cin to read input from the user

>>

200

Instead of cout we can use this output-based object to send information to the console and produce additional error diagnostics (IDE depending)

cerr

300

This header is used for file I/O

fstream

400

This datatype cannot normally gather input via the standard C++ istream

enum/enumerator

500

For how long does a standard file parse with >> last?

until EOF (end of file)

Function Junction

100

This function allows us to set a specific amount of empty spaces between outputs

setw()

200

This string function returns the index of a character within a string

string.find()

300

The functions for pow(), sqrt(), sin(), cos(), tan() are all apart of what header?

cmath

400

My enumerated function -

Color getColor(string input);

Would require what as a return?

Color type

500

This function and its namespace found within the limits header helps us validate across datatypes with cin.ignore()

numeric_limits<type>::max()

Feelin' Loopy

100

This loop is also called a post-check loop

do-while

200

an infinite loop can be purposefully made by adding what into a while loop expression?

true

300

This keyword allows me to skip the current iteration of my loop and start the next iteration

continue

400

This for loop expression counts every odd number up to 20

for(int i = 1; i < 20; i+=2)

{BONUS +200, how would this expression change if I wanted every even number up to and including 20?}

500

This while loop expression validates whether or not a character is lowercase

while(!islower(char))

Code for your life

100

string toString(int num);

string toString(bool tf);

string toString(Color color);

Use a single cout statement that calls on all 3 overloaded functions at once

cout << toString(5) << toString(true) << toString(RED);

200

Combine 2 characters into a single string.

string append(char a, char b);

string myString; myString += a;

myString += b; return myString;

{BONUS +200 - How can this be done with just a single line?}

300

string veggies = "carrot, lettuce, green beans, turnips"

Create me a substring that returns "green beans"

veggies.substr(17,11);

400

If a negative number is passed in, convert it to positive. If a positive number is passed it, return that same number. Do this in a single line

int toPositive(int num);

return num > 0 ? num : num*-1;

500

int num = 12345

move the last digit 5 to the beginning of the number. Your new number should be 51234. Keep the datatype as an int.

int num = 12345;

int lastDigit = num % 10;

int rest = num / 10;

cout << lastDigit * 10000 + rest;

{BONUS + 200, How can you do this using a more generic approach for any number given?}

Generally speaking

100

C++ commonly is associated with this programming methodology 

object oriented programming (OOP)

200

This tool converts our C++ source code to assembly code

Compiler

{BONUS +200. What is the name of the tool to convert object code to an executable file?}

300

This variable once initialized cannot be changed

Constant

400

This is another name for a fixed or hardcoded value stored within a variable

Literal

500

Converting datatypes safely and explicitly requires a what?

static_cast
