C is a powerful and popular programming language that is used to write computer programs. It was created in the 1970s by Dennis Ritchie and is still widely used today. C is often called a “low-level” language because it can work closely with a computer’s hardware, but it is also considered easy to learn compared to some other low-level languages.
Characteristic of C
Simple and Efficient: C is known for its simplicity and efficiency. It can perform tasks very quickly and gives the programmer control over how the program uses memory.
Procedural Language: C is a procedural programming language, which means it focuses on writing functions to complete tasks. Programs in C are written as a series of instructions to be executed step-by-step.
Low-Level Programming: C allows you to directly interact with memory (RAM) using pointers, making it powerful for tasks that need high performance, such as creating operating systems or embedded systems (like microcontrollers).
Portable: Programs written in C can run on different types of computers with little change to the code. This is why many operating systems, like Linux, are written in C.
Used Everywhere: C is used in many types of software, including operating systems, games, desktop applications, and more.
Why Learn C?
Foundation for Other Languages: C is the basis for many other programming languages like C++, Java, and Python. Learning C gives you a strong foundation in programming.
Performance: C is very fast, which is why it is often used for system-level programming (like operating systems).
Control: It gives you more control over how a program runs, which is important for certain tasks like creating video games or managing memory.
Pros and Cons of C language
There are many pros and cons of C language
Pros of C:
Speed: C programs run fast because they are compiled directly to machine code.
Control Over Hardware: You can manage memory and system resources directly.
Portability: C code can run on different machines with few changes.
Cons of C
Manual Memory Management: You must manage memory yourself (e.g., allocating and freeing memory), which can lead to errors if not done properly.
No Object-Oriented Features: C doesn’t have built-in features for object-oriented programming, which can make complex programs harder to manage.
C Tutorial– Questions and Answers
Q 1: What is C language?
Ans: C is a general-purpose, procedural programming language developed by Dennis Ritchie, mainly used for system and application programming.
Q 2: Why is C called a middle-level language?
Ans: C supports both low-level (memory manipulation) and high-level (functions, loops) programming features.
Q 3: What are the main features of C?
Ans: Portability, efficiency, structured programming, rich library, and fast execution.
Q 4: What are keywords in C?
Ans: Keywords are reserved words with predefined meanings, such as int, return, if, and while.
Q 5: What is a C program used for?
Ans: C is used to develop operating systems, embedded systems, compilers, and high-performance applications.
