Fortran semantics say that function arguments never alias and there is an array type, where in C arrays are pointers. This is why Fortran is often faster than C. This is why numerical libraries are still written in Fortran.
Assembly is almost pure binary so it is without bias the fastest language. C is the fastest because it's the speed of light, and relativity?
C++ is better suited for game development and application development. However, there are several differences between the two languages that make beginner programmers wonder if they should be learning C or C++.
C is a faster language compared to Python as it is compiled. Python programs are usually slower than C programs as they are interpreted. In C, the type of the various variables must be declared when they are created, and only values of those particular types must be assigned to them.

Speed: Golang compiles codes faster than C++ since it has a simple syntax. Not only that, Golang compiles codes faster with the support of Garbage collectors, concurrency options, Goroutines, and multi-core CPUs. Besides, Golang uses Goroutines and channels for compilation, whereas C++ uses threads.
Java is compiled into a lower language, then interpreted. It also has automatic garbage collection, and it's farther from machine code in the first place. Because of this C code tends to run faster than Java, but difference depends on what's being done and how well the code has been optimized.
Performance: C++ is widely used when higher level languages are not efficient. C++ code is much faster than C# code, which makes it a better solution for applications where performance is important.
In the early days of C++, it's said to be significantly slower than C. The difference was reduced over time with the development of C++. Similarly, C# was said in its early days to be significantly slower than C++.
The C programming language will turn fifty years old in 2022. Yet despite its long history, C remains one of the top "most-used" programming languages in many "popular programming languages" surveys. For example, check out the TIOBE Index, which tracks the popularity of different programming languages.
The C programming language has been alive and kicking since 1972, and it still reigns as one of the fundamental building blocks of our software-studded world.
C++ is considered to be one of the most powerful, fastest, and toughest programming languages.
C++ is often faster than PL/SQL; though generally harder to write. Again it comes down a lot to what you're doing; for most applications the complexity of using C/C++ over PL/SQL outweighs any performance benefits.
Fortran semantics say that function arguments never alias and there is an array type, where in C arrays are pointers. This is why Fortran is often faster than C. This is why numerical libraries are still written in Fortran. However, it comes at the cost of pointer arithmetic.
Rust incorporates a memory ownership model enforced at a compile time. Since this model involves zero runtime overhead, programs written in Rust are not only memory-safe but also fast, leading to performance comparable to C and C++.
In conclusion, you can, in theory, create C# code that's just as fast as C++ code. But, in most cases, C++ code is going to be faster because of coding habits.
As a compiled language, C# converts directly into machine code that a processor can execute. No interpreter needed. In some cases, this means that C# code can run up to 44 times faster than Python. And whilst you can speed up Python's performance significantly with PyPy's JIT compiler, C# still holds its lead here.
Compiled Go code is generally slower than C executables.
C++ is used more in large-scale development, like for banks or governments, whereas Java creates more consumer products like apps, software, and video games. Java is ideal for creating simple mobile applications, so if your ideal job is to become a freelance app creator, Java is where you should start.
C# vs Java: performance
However, according to benchmarks around the web, C# tends to perform better overall. Its response time is shorter, besides taking up less CPU load. To note fairly, when coupled together with Just-In-Time compilers, Java provides high performance too.
Java is more data-oriented. C is a middle-level language because binding of the gaps takes place between machine level language and high-level languages. Java is a high-level language because translation of code takes place into machine language using compiler or interpreter.
Especially compared to C++, Go is remarkably simple and small: there's just a lot less to learn. If you're interested in operating systems or game programming, you'll need to learn C and C++ at some point, but you'll have a much easier time learning those languages if you start with Go first.
Google conceived of Go as a replacement for C++, the same motivations behind another major language: Rust. Go's initial approach was celebrated: something straightforward, easy to learn, and simple to understand.
Golang doesn't rely on a virtual machine for code compilation and is directly compiled from the binary file. That's why it is much faster than Java when it comes to application development. Golang's automatic garbage collection also contributes to its speed and makes it much faster than Java.
