In-depth analysis of the correlation between Go language and C language

The Go language has similarities with the C language in terms of syntax, data types, and memory management. Although both use C-style syntax and similar data types, the Go language introduces new types such as slices and channels. In addition, Go language uses garbage collection mechanism, while C language requires manual memory management. For example, when printing "Hello, world!", Go uses fmt.Println(), while C uses printf(). When calculating Fibonacci numbers, the recursive algorithms of the two are also similar. However, the Go language is more efficient when writing modern applications because it integrates concurrency and garbage collection mechanisms.

In-depth analysis of the correlation between Go language and C language

Language level

Go language and C language have both syntax and semantics Have similarities. They all use C-style syntax, for example:

// Go 语言
func main() {
  fmt.Println("Hello, world!")
}

// C 语言
int main() {
  printf("Hello, world!\n");
}

Data type

Both Go language and C language support similar data types, for example:

Go language	C language
int	int
float64	double
bool	_bool
string	char *

In addition, the Go language also introduces new data types such as slices and channels.

Memory Management

The Go language uses a garbage collection mechanism to automatically manage memory. When an object is no longer needed, the garbage collector automatically releases the memory it occupies. C, on the other hand, requires manual memory management. Developers must use the malloc() and free() functions to allocate and free memory.

Practical Case

Example 1: Print "Hello, world!"

// Go 语言
package main

import "fmt"

func main() {
  fmt.Println("Hello, world!")
}

// C 语言
#include <stdio.h>

int main() {
  printf("Hello, world!\n");
  return 0;
}

Example 2: Calculate Fibonacci Sequence

// Go 语言
package main

func fibonacci(n int) int {
  if n <= 1 {
    return n
  }
  return fibonacci(n-1) + fibonacci(n-2)
}

func main() {
  result := fibonacci(5)
  fmt.Println("Fibonacci number at position 5:", result)
}

// C 语言
#include <stdio.h>

int fibonacci(int n) {
  if (n <= 1)
    return n;
  return fibonacci(n - 1) + fibonacci(n - 2);
}

int main() {
  int result = fibonacci(5);
  printf("Fibonacci number at position 5: %d\n", result);
  return 0;
}

Through these examples, we can see that the Go language and the C language are similar in many aspects. However, the Go language also introduces new features, such as garbage collection and concurrency, to make it more efficient and safer when writing modern applications.
