C language is a general-purpose, procedural programming language. In 1972, Dennis Ritchie designed and developed the C language at Bell Telephone Laboratories for the purpose of porting and developing the UNIX operating system.

Students use C to learn programming, but its role goes far beyond that. It is not only an academic language. It is not the simplest language because C is a very low-level programming language.

Today, C is widely used in embedded devices and drives the majority of Internet servers built with Linux. The Linux kernel is written in C, which also means that C drives the kernel of all Android devices. It can be said that at this moment, a large part of the world is running on C code, which is amazing.

C brought an easy-to-implement language, and its compiler could be easily ported to different machines.

  • C is a compiled language, like Go, Java, Swift, or Rust. Other popular languages, such as Python, Ruby, or JavaScript, are interpreted languages. The difference between compiled languages and interpreted languages is constant: compiled languages generate binary files that can be directly executed and distributed.
  • C does not support garbage collection, which means we must manage memory ourselves. Managing memory is a complex task that requires extreme care to prevent defects, but C has become the ideal language for embedded device programming, such as Arduino.
  • C does not hide the complexity and capabilities of the lower-level machine. Once you know what you can do, you can have tremendous power.
  • C programming is considered the foundation of other programming languages, which is why it is called the mother tongue.

C language can be defined in the following ways:

  •  The foundation of all modern programming languages
  • System programming language
  • Procedural programming language
  • Structured programming language
  • Intermediate programming language.

The Difference Between C Program and C++ Program in Tablet Format

C Program C++ Program
C is a procedural programming language. C++ is an object-oriented programming language.
C programs use functions to organize code. C++ programs use classes to organize code.
C does not support function overloading. C++ supports function overloading.
C does not support namespaces. C++ supports namespaces.
C does not support exception handling. C++ supports exception handling.
C programs use structures to group related data. C++ programs use classes to group related data and functions.
C programs have simpler syntax and fewer keywords. C++ programs have more complex syntax and more keywords.
C does not support templates. C++ supports templates.
C programs are typically faster and more efficient. C++ programs are typically slower and less efficient due to the additional overhead of object-oriented features.

the Difference Between C Program and Python Program

C Program Python Program
C is a compiled language, which means that the code needs to be compiled before it can be executed. Python is an interpreted language, which means that the code can be executed directly without needing to be compiled.
C is a statically typed language, which means that the data type of a variable must be declared before it can be used. Python is a dynamically typed language, which means that the data type of a variable is determined at runtime.
C is a low-level language, which means that it gives the programmer direct access to the computer’s hardware. Python is a high-level language, which means that it provides a lot of built-in functionality that makes programming easier and more efficient.
C programs typically require more lines of code to achieve the same result as a Python program. Python programs are typically shorter and more concise than C programs.
C programs can be more efficient than Python programs because C code can be optimized to take advantage of the computer’s hardware. Python programs can be less efficient than C programs because they run in a virtual machine and are subject to interpretation overhead.
C has a more limited standard library than Python, which means that developers need to write more code from scratch. Python has a comprehensive standard library that provides a wide range of built-in functionality.
C is often used for system-level programming, such as operating systems, device drivers, and embedded systems. Python is often used for web development, data analysis, scientific computing, and artificial intelligence.
