Performance comparison: speed and efficiency of Go language and C language
In the field of computer programming, performance has always been an important indicator that developers pay attention to. When choosing a programming language, developers usually focus on its speed and efficiency. Go language and C language, as two popular programming languages, are widely used for system-level programming and high-performance applications. This article will compare the performance of Go language and C language in terms of speed and efficiency, and demonstrate the differences between them through specific code examples.
First, let’s take a look at the overview of Go language and C language. Go language is a statically typed, compiled, and highly concurrency programming language developed by Google. It is committed to simplifying concurrent programming and provides powerful standard library support. The C language is a general-purpose high-level programming language that is widely used in system programming and low-level development. It has efficient performance and flexible features.
In terms of speed, C is generally considered a performant language. Due to its close-to-low-level programming characteristics, C language code can be optimized very efficiently. In comparison, the Go language performs quite well in terms of speed. Its compiler and runtime system are optimized to handle concurrent tasks efficiently. Although Go language may not be as fast as C language, in practical applications, it can still provide sufficient performance.
Next, we will compare the performance of Go language and C language in terms of speed and efficiency through specific code examples. First is a simple example of calculating the Fibonacci sequence:
Go language code example:
package main
import "fmt"
func fibonacci(n int) int {
if n <= 1 {
return n
}
return fibonacci(n-1) + fibonacci(n-2)
}
func main() {
fmt.Println(fibonacci(40))
}C language code example:
#include <stdio.h>
int fibonacci(int n) {
if (n <= 1) {
return n;
}
return fibonacci(n-1) + fibonacci(n-2);
}
int main() {
printf("%d
", fibonacci(40));
return 0;
}In the above example, We calculate the 40th number in the Fibonacci sequence. By comparing the execution times of the two languages, we can see that C language is significantly faster than Go language in this example.
Another example is the operation of summing two large arrays:
Go language code example:
package main
import (
"fmt"
"time"
)
func sumArray(arr []int) int {
sum := 0
for _, num := range arr {
sum += num
}
return sum
}
func main() {
arr := make([]int, 1000000000)
for i := range arr {
arr[i] = i
}
start := time.Now()
fmt.Println(sumArray(arr))
fmt.Println("Time taken:", time.Since(start))
}C language code example:
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
int sumArray(int *arr, int size) {
int sum = 0;
for (int i = 0; i < size; i++) {
sum += arr[i];
}
return sum;
}
int main() {
int size = 1000000000;
int *arr = (int *)malloc(size * sizeof(int));
for (int i = 0; i < size; i++) {
arr[i] = i;
}
clock_t start = clock();
printf("%d
", sumArray(arr, size));
double time_taken = ((double)clock() - start) / CLOCKS_PER_SEC;
printf("Time taken: %f seconds
", time_taken);
return 0;
}By comparing the execution times of the two examples above, we can see that C language is more efficient when processing large amounts of data. This is mainly due to the underlying performance of C language and the flexibility of pointer operations.
To sum up, Go language and C language have their own advantages and disadvantages in terms of speed and efficiency. When choosing a programming language, developers need to weigh the pros and cons of the two based on specific needs and application scenarios, and choose the most suitable language to complete the task.

.NET Core Quick Start Tutorial 1. The beginning: Talking about .NET Core
May 07, 2025 pm 04:54 PM
1. The Origin of .NETCore When talking about .NETCore, we must not mention its predecessor .NET. Java was in the limelight at that time, and Microsoft also favored Java. The Java virtual machine on the Windows platform was developed by Microsoft based on JVM standards. It is said to be the best performance Java virtual machine at that time. However, Microsoft has its own little abacus, trying to bundle Java with the Windows platform and add some Windows-specific features. Sun's dissatisfaction with this led to a breakdown of the relationship between the two parties, and Microsoft then launched .NET. .NET has borrowed many features of Java since its inception and gradually surpassed Java in language features and form development. Java in version 1.6
How to understand ABI compatibility in C?
Apr 28, 2025 pm 10:12 PM
ABI compatibility in C refers to whether binary code generated by different compilers or versions can be compatible without recompilation. 1. Function calling conventions, 2. Name modification, 3. Virtual function table layout, 4. Structure and class layout are the main aspects involved.
Four ways to implement multithreading in C language
Apr 03, 2025 pm 03:00 PM
Multithreading in the language can greatly improve program efficiency. There are four main ways to implement multithreading in C language: Create independent processes: Create multiple independently running processes, each process has its own memory space. Pseudo-multithreading: Create multiple execution streams in a process that share the same memory space and execute alternately. Multi-threaded library: Use multi-threaded libraries such as pthreads to create and manage threads, providing rich thread operation functions. Coroutine: A lightweight multi-threaded implementation that divides tasks into small subtasks and executes them in turn.
How to use the chrono library in C?
Apr 28, 2025 pm 10:18 PM
Using the chrono library in C can allow you to control time and time intervals more accurately. Let's explore the charm of this library. C's chrono library is part of the standard library, which provides a modern way to deal with time and time intervals. For programmers who have suffered from time.h and ctime, chrono is undoubtedly a boon. It not only improves the readability and maintainability of the code, but also provides higher accuracy and flexibility. Let's start with the basics. The chrono library mainly includes the following key components: std::chrono::system_clock: represents the system clock, used to obtain the current time. std::chron
distinct function usage distance function c usage tutorial
Apr 03, 2025 pm 10:27 PM
std::unique removes adjacent duplicate elements in the container and moves them to the end, returning an iterator pointing to the first duplicate element. std::distance calculates the distance between two iterators, that is, the number of elements they point to. These two functions are useful for optimizing code and improving efficiency, but there are also some pitfalls to be paid attention to, such as: std::unique only deals with adjacent duplicate elements. std::distance is less efficient when dealing with non-random access iterators. By mastering these features and best practices, you can fully utilize the power of these two functions.
What is sum generally used for in C language?
Apr 03, 2025 pm 02:39 PM
There is no function named "sum" in the C language standard library. "sum" is usually defined by programmers or provided in specific libraries, and its functionality depends on the specific implementation. Common scenarios are summing for arrays, and can also be used in other data structures, such as linked lists. In addition, "sum" is also used in fields such as image processing and statistical analysis. An excellent "sum" function should have good readability, robustness and efficiency.
Where is the C language function library? How to add the C language function library?
Apr 03, 2025 pm 11:39 PM
The C language function library is a toolbox containing various functions, which are organized in different library files. Adding a library requires specifying it through the compiler's command line options, for example, the GCC compiler uses the -l option followed by the abbreviation of the library name. If the library file is not under the default search path, you need to use the -L option to specify the library file path. Library can be divided into static libraries and dynamic libraries. Static libraries are directly linked to the program at compile time, while dynamic libraries are loaded at runtime.
