About the test:

The C++ Online Test uses scenario-based and code tracing MCQ questions to evaluate a candidate's ability to write C++ programs (data types, functions, data structures, STL), structure the code using Object-oriented programming principles (classes, inheritance, polymorphism, overloading), handle exceptions and manage memory. The test uses coding questions to evaluate hands-on C++ coding skills.

Covered skills:

  • C++ basics (Data Types; Variables; Operators)
  • modules and data structures
  • Functions
  • Pointers and references

Adaface C ++ online test is the most accurate way to shortlist C++ Developers



Reason #1

Tests for on-the-job skills

C ++ online -testen hjælper rekrutterere og ansættelsesledere med at identificere kvalificerede kandidater fra en pulje af CV og hjælper med at tage objektive ansættelsesbeslutninger. Det reducerer den administrative omkostning ved at interviewe for mange kandidater og sparer dyre teknisk tid ved at filtrere ukvalificerede kandidater.

Testskærmene kandidater til følgende færdigheder:

  • C ++ Fundamentals (variabler, forgrening og looping, funktioner, referenceparametre, arrays, strenge, vektorer)
  • I/O -drift på filer og I/O -streams
  • Hukommelsesstyring, inklusive pointers, referencer, flytning og kopi -konstruktører
  • Ups -koncepter (klasser, overbelastning af operatør, sammensætning, arv, polymorfisme, skabeloner, samtidighed osv.)
  • Implementering af almindelige datastrukturer og algoritmer
  • Effektiv brug af indbyggede funktioner og tip
  • Standardskabelonbiblioteksklasser (vektorer, sæt, køer)
  • Bibliotekværktøjer - Tuples, par, dato og tid
  • Håndtering af undtagelser
Reason #2

No trick questions

Traditional assessment tools use trick questions and puzzles for the screening, which creates a lot of frustration among candidates about having to go through irrelevant screening assessments.

The main reason we started Adaface is that traditional pre-employment assessment platforms are not a fair way for companies to evaluate candidates. At Adaface, our mission is to help companies find great candidates by assessing on-the-job skills required for a role.

Why we started Adaface ->
Reason #3

Non-googleable questions

We have a very high focus on the quality of questions that test for on-the-job skills. Every question is non-googleable and we have a very high bar for the level of subject matter experts we onboard to create these questions. We have crawlers to check if any of the questions are leaked online. If/ when a question gets leaked, we get an alert. We change the question for you & let you know.

Dette er kun en lille prøve fra vores bibliotek med 10.000+ spørgsmål. De faktiske spørgsmål om dette C++ Online Test vil være ikke-gåbart.

Registration Queue
Logic
Solve
We want to register students for the next semester. All students have a receipt which shows the amount pending for the previous semester. A positive amount (or zero) represents that the student has paid extra fees, and a negative amount represents that they have pending fees to be paid. The students are in a queue for the registration. We want to arrange the students in a way such that the students who have a positive amount on the receipt get registered first as compared to the students who have a negative amount. We are given a queue in the form of an array containing the pending amount.
For example, if the initial queue is [20, 70, -40, 30, -10], then the final queue will be [20, 70, 30, -40, -10]. Note that the sequence of students should not be changed while arranging them unless required to meet the condition.
⚠️⚠️⚠️ Note:
- The first line of the input is the length of the array. The second line contains all the elements of the array.
- The input is already parsed into an array of "strings" and passed to a function. You will need to convert string to integer/number type inside the function.
- You need to "print" the final result (not return it) to pass the test cases.

For the example discussed above, the input will be:
5
20 70 -40 30 -10

Your code needs to print the following to the standard output:
20 70 30 -40 -10

Solve
A startup company E-Motors is building driverless automated cars. The car contains a sensor that checks the road quality for the next N meters to decide the optimal speed at which the cars should move. We are given recorded data by the sensor in the form of an array, where each element of the array is the rating given to 1 meter of the road in sequence. 

The rating given by the sensor is from 1 to 100, where 100 represents the road with the best condition, and any rating above 60 is optimal. Find the longest stretch of road in meters that is categorized as optimal by the sensor.

The input is an array of "strings" which needs to be converted from string to integer/number inside the function.

Visitors Count
Strings
Solve
A manager hires a staff member to keep a record of the number of men, women, and children visiting the museum daily. The staff will note W if any women visit, M for men, and C for children. You need to write code that takes the string that represents the visits and prints the count of men, woman and children. The sequencing should be in decreasing order. 
Example:

Input:
WWMMWWCCC

Expected Output: 
4W3C2M

Explanation: 
‘W’ has the highest count, then ‘C’, then ‘M’. 
⚠️⚠️⚠️ Note:
- The input is already parsed and passed to a function.
- You need to "print" the final result (not return it) to pass the test cases.
- If the input is- “MMW”, then the expected output is "2M1W" since there is no ‘C’.
- If any of them have the same count, the output should follow this order - M, W, C.

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment C++ Online Test in your hiring process is that it is an elimination tool, not a selection tool. In other words: you want to use the test to eliminate the candidates who do poorly on the test, not to select the candidates who come out at the top. While they are super valuable, pre-employment tests do not paint the entire picture of a candidate’s abilities, knowledge, and motivations. Multiple easy questions are more predictive of a candidate's ability than fewer hard questions. Harder questions are often "trick" based questions, which do not provide any meaningful signal about the candidate's skillset.

Reason #6

1 click candidate invites

Email invites: You can send candidates an email invite to the C++ Online Test from your dashboard by entering their email address.

Public link: You can create a public link for each test that you can share with candidates.

API or integrations: You can invite candidates directly from your ATS by using our pre-built integrations with popular ATS systems or building a custom integration with your in-house ATS.

Reason #7

Detailed scorecards & comparative results

Reason #8

High completion rate

Adaface tests are conversational, low-stress, and take just 25-40 mins to complete.

This is why Adaface has the highest test-completion rate (86%), which is more than 2x better than traditional assessments.

Reason #9

Advanced Proctoring


Hvordan adskiller testen sig for senior C ++ -udviklere?

Vores emneeksperter tilpasser testen i henhold til anciennitet på to måder:

  • De emner, der er valgt til seniorudviklere, vil være af højere niveau, mens emnerne for juniorudviklere vil være omkring grundlæggende grundlæggende. Dette vil sikre, at seniorudviklere testes på on-the-job-færdigheder, som de forventes at have
  • Sværhedsgrad af spørgsmål vil blive varieret baseret på anciennitetsniveauet. På denne måde er seniorudviklere overvåget ved en dybdegående brug af de centrale emner, mens juniorudviklere er overvåget om viden om kerneemner

Her er et par emner vurderet i seniorudviklervurderinger:

  • C ++ Concurrency (Threads, Mutex, Package_Task, Future, Async, Promise)
  • Låsbaseret trådsikker implementering af datastrukturer

C++ Online Test FAQs

Kan jeg evaluere C ++ og indlejret C i den samme test?

Ja. Du kan gennemgå vores standard Embedded C-test for at få en fornemmelse af, hvordan indlejret C evalueres. Den endelige vurdering ville have spørgsmål til evaluering af indlejret C, C ++ og kodningsevner.

Kan jeg kombinere flere færdigheder i en brugerdefineret vurdering?

Ja absolut. Brugerdefinerede vurderinger er oprettet baseret på din jobbeskrivelse og vil omfatte spørgsmål om alle must-have-færdigheder, du angiver.

Har du nogen anti-cheating eller proctoring-funktioner på plads?

Vi har følgende anti-cheating-funktioner på plads:

  • Ikke-gåbare spørgsmål
  • IP Proctoring
  • Webproctoring
  • Webcam Proctoring
  • Detektion af plagiering
  • Sikker browser

Læs mere om Proctoring Features.

Hvordan fortolker jeg testresultater?

Den primære ting at huske på er, at en vurdering er et elimineringsværktøj, ikke et udvælgelsesværktøj. En færdighedsvurdering er optimeret for at hjælpe dig med at eliminere kandidater, der ikke er teknisk kvalificerede til rollen, den er ikke optimeret til at hjælpe dig med at finde den bedste kandidat til rollen. Så den ideelle måde at bruge en vurdering på er at beslutte en tærskelværdi (typisk 55%, vi hjælper dig med benchmark) og inviterer alle kandidater, der scorer over tærsklen for de næste interviewrunder.

Hvilken oplevelsesniveau kan jeg bruge denne test til?

Hver Adaface -vurdering tilpasses til din jobbeskrivelse/ ideel kandidatperson (vores emneeksperter vælger de rigtige spørgsmål til din vurdering fra vores bibliotek på 10000+ spørgsmål). Denne vurdering kan tilpasses til ethvert erfaringsniveau.

Får hver kandidat de samme spørgsmål?

Ja, det gør det meget lettere for dig at sammenligne kandidater. Valgmuligheder for MCQ -spørgsmål og rækkefølgen af ​​spørgsmål randomiseres. Vi har anti-cheating/proctoring funktioner på plads. I vores virksomhedsplan har vi også muligheden for at oprette flere versioner af den samme vurdering med spørgsmål om lignende vanskelighedsniveauer.

Jeg er kandidat. Kan jeg prøve en øvelsestest?

Nej. Desværre understøtter vi ikke praksisforsøg i øjeblikket. Du kan dog bruge vores eksempler på spørgsmål til praksis.

Hvad er omkostningerne ved at bruge denne test?

Du kan tjekke vores prisplaner.

Kan jeg få en gratis prøve?

Ja, du kan tilmelde dig gratis og forhåndsvise denne test.

Jeg flyttede lige til en betalt plan. Hvordan kan jeg anmode om en brugerdefineret vurdering?
