C Coding Assessment #

Coding assessments in the C programming language are a valuable tool for hiring software engineers and entry-level graduates from computer science programs. C is considered the foundation for many other programming languages, including object-oriented languages, making it an essential skill for any software developer. The language is known for its power and flexibility, making it a popular choice for system programming, compiler development, and networking applications.

In face-to-face interviews, it can be difficult to gauge a candidate’s proficiency in C programming. Online coding assessments provide a way to objectively evaluate a candidate’s knowledge and skills in the language. These assessments can take the form of multiple-choice questions, fill-in-the-blank questions, or coding exercises that require candidates to write and debug programs in C.

One of the advantages of online coding assessments is that they can be automatically graded using online compilers. These compilers can execute the candidate’s program and compare its output to the expected results, providing an objective measure of the candidate’s proficiency in the language.

In summary, using coding assessments in the C programming language can be a useful tool to assess candidates’ knowledge of the language and make more informed hiring decisions. The language is widely used and having a good understanding of it is crucial for software development, system programming, compiler development, and networking applications.

You can also conduct Online Coding Test where candidates need to write and compile the code

Sample C Language Coding Question

Write a program that takes an integer input from the user and calculates its factorial. The program should then print the result to the screen.

Test Cases:

Input: 5

Expected Output: 120

Input: 6

Expected Output: 720

Input: 8

Expected Output: 40320

The candidate would need to write a code in C, Compile it and then run it with the inputs provided and need to check the output with the expected output.

Here’s one possible implementation of the program in C language:

#include <stdio.h>

int main()

{

    int input, factorial = 1;

    printf(“Enter an integer: “);

    scanf(“%d”, &input);

    for (int i = 1; i <= input; i++) {

        factorial *= i;

    }

    printf(“The factorial of %d is %d”, input, factorial);

    return 0;

}
