C is a general-purpose, procedural programming language developed in the early 1970s by Dennis Ritchie at Bell Labs. It was initially created for the UNIX operating system but has since become a foundation for various other languages and operating systems.
Key points about C programming language:
- Procedural Language: C is a procedural programming language, emphasizing functions and structured programming.
- Developed in the 1970s: Dennis Ritchie at Bell Labs created C as an evolution of the B language.
- Foundation for Modern Languages: Many contemporary languages, like C++, C#, and Java, have roots in C.
- System Programming: C is commonly used for low-level system programming, such as writing operating system kernels.
- Portable and Efficient: With minimal runtime requirements, C code can run efficiently across various computer platforms.
- Rich Library Support: C offers a comprehensive set of built-in libraries that provide essential functions and methods, simplifying complex tasks.
- Pointers and Memory Management: C provides direct access to memory through pointers, allowing for dynamic memory allocation and manipulation.
- Modularity: Functions and data blocks can be maintained separately in C, promoting reusability and organized code.
- Wide Applications: Beyond system programming, C is used in applications, game development, embedded systems, and more.
- Ubiquity in Curricula: Being foundational, C programming is often the introductory language in computer science and engineering courses worldwide.

The C Programming Language Certified Associate (CLA) certification is a recognized credential for aspiring C programmers. It tests proficiency in the foundational aspects of C programming. Here, we have compiled a practice test of 25 multiple-choice questions, complete with answers and explanations, to help you prepare for the exam. 1. Which of the following is
In C, decision-making structures (like if, if-else, and switch) allow a program to take a path out of several depending on the outcome of an expression or a condition. Loops (like for, while, and do-while) let a part of the code run multiple times based on a condition. Let’s dive into C’s decision-making constructs and
Loops form the backbone of many algorithms and routines in the C language. They allow you to run a section of code repeatedly until a certain condition is met. If you’re eager to test your knowledge of C loops, you’re in the right place! Let’s dive into this multiple-choice quiz. Each question is followed by
In C, a pointer is a variable that stores the memory address of another variable. Using pointers, you can directly interact with memory locations, enabling various operations like dynamic memory allocation, array iterations, and function arguments passed by reference. Let’s dive into the world of pointers in C and assess your comprehension with some multiple
Operators are symbols that instruct the compiler to perform specific mathematical or logical functions. They can be categorized into Arithmetic, Relational, Logical, Bitwise, Assignment, and Miscellaneous operators.
