What is C Programming Language? What Is The Difference Between C and C++?

The C Programming Language began to be used in 1972, and it is firmly established as one of the core components in this era of moving to software.

The C language is a programming language designed by Ken Thompson and Dennis Rich in 1972 to create a Unix operating system when working at Bell Labs.

But why is it C, not A? Initially, Ken Thompson developed the B language (according to the first letter B of the Bell Labs, written in B language) by refining the BCPL language to taste, and later Dennis Rich improved the B language to create the C language.


However, there are techniques that survive for a long time because people don't feel the need to replace them. Many other languages ​​have emerged over the past few decades, some of which have explicitly challenged C's thing. Some of them gained popularity and ate little by little from the edge of C.


It is not difficult to argue for the need to replace C. There are ways to study programming languages, software development practices, and much better than C. However, the status of C supported by decades of research and development remains the same.


C is superior to other languages ​​in performance, mechanical compatibility, and universality. It would be meaningful to compare C with other major languages.

What Is The Difference Between C and C++?


The Difference Between C and C++?


C's most common comparison is, of course, C ++. As the name suggests, C ++ was developed as an extension of C. To summarize the difference between C ++ and C, it can be said to be broad or excessive for some people who accept it.


The syntax and approach are similar to C, but C ++ has many really useful features that C doesn't natively provide, such as namespaces, templates, exceptions, and automatic memory management.

Projects that require top-level performance, such as databases or machine learning systems, are often written using these features of C ++ to take full advantage of the system's full performance.


In addition, C ++ continues to expand much more aggressively than C. The upcoming C ++ 20 will provide even more new features, including concepts that make modules, coroutines, synchronization libraries, and templates easier to use.


On the other hand, looking at the latest revision of the C standard, there are few additional features and the focus is on maintaining backward compatibility.


All of the advantages of C ++ are also disadvantages at the same time. The more you use C ++ features, the higher the complexity and the more difficult it is to control the results.


Developers can avoid most of the biggest pitfalls and excesses of C ++ by using only certain parts of C ++. Some companies are fundamentally blocking the complexity of C ++. By sticking to C, developers only work within a subset of C. The Linux kernel development team, for example, avoids C ++.


A way to avoid the excess of C ++ is to choose C to accommodate compulsory minimalism. It's better not only for those who write code but also for developers who need to maintain this code in the future.


Of course, C ++ has a wealth of high-level features that have their own uses. However, if minimalism is better suited for current and future projects and project teams, C is a more viable option.

What Is The Difference Between C and Java


Java is still the mainstay of enterprise software development and continues to be a leader in overall development decades after its birth. Many of the most important enterprise software projects, including the majority of the Apache Software Foundation projects, are written in Java and are still a prominent language when developing new projects with enterprise-class requirements.


Java syntax borrows a significant portion of C and C ++. However, unlike C, Java is not compiled natively by default. Instead, the Java runtime environment, JVM, and Just-In-Time (JIT) are compiled to run in the target environment. Java code compiled with JIT under appropriate conditions may approach or exceed the performance of C.


Also, thanks to Java's basic principle of "write once and run everywhere", Java programs can run on a variety of target architectures with a relatively little tweaking. Although C has been ported to quite a number of architectures, it is often necessary to customize C programs, for example, from Linux to Windows to run properly.


Thanks to this combination of portability and powerful performance, and the vast software library and framework ecosystem, Java is the preferred language and runtime for building enterprise applications.


Java's downside to C is that it runs in close proximity to the machine or directly handles the hardware, which is not the primary focus of Java. C code is compiled into machine code and executed directly by the process.


Java is compiled into intermediate code, bytecode, and the JVM interpreter converts the bytecode into machine code. In addition, Java's automatic memory management is useful in most environments, but C is better for programs that require optimal use of limited memory resources.


Still, there are a few areas where Java comes close to C in terms of speed. The JVM's JIT engine optimizes routines at run time based on program behavior to achieve a wide variety of optimizations not possible with precompiled C.


In addition, the Java runtime automates memory management, and some new applications work around it. Apache Spark, for example, optimizes in-memory processing using a custom memory management code that avoids the JVM.

C vs. C # and .Net


The C # and .NET frameworks have been released and have been used as major languages ​​to incorporate software for nearly 20 years. It is usually said to be Microsoft's response to Java over C # and .NET (managed code compiler system and universal runtime).


Also, there are as many comparisons between C and C # / Net as C and Java.


Like Java (and parts of Python), .Net provides cross-platform portability and a vast integrated software ecosystem. Given how much business development is taking place in the .NET field, it is by no means a small advantage.


When developing programs in C # or other .NET languages, you can take advantage of the myriad of tools and libraries written for the .NET runtime.


Another .NET advantage similar to Java is JIT optimization. C # and .NET programs can be precompiled like C, but they are mainly compiled into JIT by the .NET runtime and optimized using runtime information. JIT compilation allows for instant optimization of various kinds of .NET programs that cannot be performed in C.


C # and .NET, like C, provide a variety of mechanisms for direct memory access. Heap, Stack, unmanaged system memory, all accessible through the .NET API and objects. Developers can also use .Net's unsafe mode to further improve performance.


It's not just about merit. You cannot arbitrarily exchange managed and unsafe objects, and marshaling between the two affects performance. Therefore, maximizing the performance of .NET applications means minimizing the movement between managed and unmanaged objects.


C is required if the disadvantage between managed and unmanaged memory is unacceptable, or if the .NET runtime is not suitable for the target environment (eg kernel space) or not provided at all. Unlike C # and .NET, direct memory access is disabled in C by default.

The old syntax has many elements from C, such as curly braces that act as separators and semicolons that terminate the statement. Even considering new high-level features such as namespaces and package management, developers who are proficient in C can usually use high without much difficulty.
