5C++ Questions

1. What will the following code print?
num = 8;
cout << --num << " ";
cout << num++ << " ";
cout << num;

2.Since the while loop evaluates the condition before executing the statement(s), it is known as a(n)____ loop, whereas the do-while loop evaluates the condition after the statements have been executed, it is known as a(n)____ loop.

3.T/F While loops can only be used when a counter is decremented to zero. If the counter is incremented you must use the do-while loop.

4.How many times will the following program print Hello?

counter = 3; 
while (counter > 0) {
    loop = 5;
    while (loop > 0) {
          cout << "Hello" << endl;
          loop--;
     }
     counter--;
}

5.If nothing within a while loop causes the condition to become false, a(n) ________ may occur.

6.The -- operator ... (check all that apply)

7.Which of the following statements will result in an infinite loop.

x = 10; 

while (x >= 0) {

    cout << x;
    ++x; 
}

x = 10; 

while (x >= 0) {

    cout << x;

}

x = 0; 

while (x <= 10) {

    cout << x;
    x = 10;

}

x = 10; 

while (x >= 0); {

    cout << x;
    x--;
}

8.T/F In C++, a file must be opened before the contents can be read.

9. T/F In C++, a file must exists before it can be written to.

10.Which of the following statements show the proper way to use the increment (++) operator.

<Haskell>

Define an action adder :: IO () that reads a given number of integers from the keyboard, one per line, and displays their sum. For example: > adder

How many numbers? 5

1 3 5 7 9

The total is 25

Hint: start by defining an auxiliary function that takes the current total and how many numbers remain to be read as arguments. You will also likely need to use the library functions read and show.

import kotlinx.coroutines.*

// TODO 1
fun sum(valueA: Int, valueB: Int): Int {
    return 0
}

// TODO 2
fun multiple(valueA: Int, valueB: Int): Int {
    return 0
}

fun main() = runBlocking {

    println("Counting...")

    val resultSum = async { sum(10, 10) }
    val resultMultiple = async { multiple(20, 20) }

    // TODO 3
    println()
}

TODO 1:
Change it to suspend function with the following conditions:
Has a waiting time of 3 seconds before the next operation runs.
Returns the value of the sum of valueA and valueB.

TODO 2:
Change it to suspend function with the following conditions:
Has a waiting time of 2 seconds before the next operation runs.
Returns the value of the multiplication valueA and valueB.

TODO 3:
Add a function to print the deferred values of the resultSum and resultMultiple variables on the console.

If run, the console will display the text:
Counting ...
Result sum: 20
Multiple results: 400

**I need to make this program to make sure that the numbers are unique. In another word, if the number has been generated and appear early, it should continue to find the next number until the number is unique.

Hint: use the array to check whether the number has been generated.

#include <iostream>

#include <cstdlib>

#include <ctime>

using namespace std;

int main() {

srand(time(NULL));

int n, low, high;

cout << "Enter how many random numbers you would like to see: ";

cin >> n;

cout << "Enter the lower limit now: ";

cin >> low;

cout << "And now enter the higher limit: ";

cin >> high;

cout << n << " random numbers:";

for (int i = 0; i < n; ++i) {

cout << " " << low + (rand() % (high-low+1)) << endl;

}

cout << endl;

return 0;

}

Please show me how it can be done and explain code needed if possible. Thanks!

fun main() {
    val stringResult = getResult("Kotlin")
    val intResult = getResult(100)

    // TODO 2
    println()
}

// TODO 1
fun <T> getResult(args: T): Int {
    return 0
}

TODO 1:
Create a new generics function with the following conditions:
The function name is getResult.
Has one type of parameter.
If the attached argument is of type Int, then the value returned is the value of the argument multiplied by 5.
If the attached argument is of type String, the value returned is a character length.
If the attached argument is of type other than Int and String, then the returned value is 0.

TODO 2:
Add functions to print the values of the stringResult and intResult variables in the console.

C++ How do I initialize a clock to 0 and run it constantly throughout the program? THEN, how do I get the time at that moment multiple times? As in id like to set the

clock = 0,

do stuff

do stuff

get time now, store it

do stuff

get time now, store it

then also be able to do arithmetic on it, for instance, last time - current time = 2 seconds. I made it sound complicated but I believe this is very easy.

// TODO 1

class Cat(private val name: String) {

var sleep: Boolean = false

fun toSleep() {

println()

}

}

fun main() {

// TODO 2

val gippy = Cat("")

gippy.toSleep()

gippy.sleep = true

gippy.toSleep()

}

TODO 1:

Complete the code in the Cat class with the following conditions:

Create a getter setter function for the sleep property in which there is a function to print text:

The getter / setter function is called

Add code to the toSleep () function to print text:

[name], sleep!

if sleep is true and text:

name, let's play!

if sleep is false.

TODO 2:

Complete initialization with Cat class.

If run the console will display text like the following:

The getter function is called

Gippy, let's play!

The setter function is called

The getter function i

Determine the computational complexity of the following language:

0ⁿ1ⁿ

^"Computational complexity theory focuses on classifying computational problems according to their inherent difficulty, (how difficult they are to solve) and relating these classes to each other. A computational problem is a task solved by a computer. Some computational problems are impractical as the known algorithm takes too much time and memory to complete."
