The similarities and differences between Go language and C language from a grammatical perspective

Go language and C language are two very popular programming languages. They have many similarities and differences in syntax. This article will compare the similarities and differences between Go language and C language from a grammatical perspective, and demonstrate the differences and commonalities between them through specific code examples.

First of all, let us take a look at the similarities and differences between Go language and C language in terms of variable declaration and assignment.

In Go language, variable declaration and assignment can be completed together, such as:

var a int = 10

In C language, declaration and assignment are usually required separately, as shown below:

int a;
a = 10;

This is because the design concept of Go language is to be concise and clear, minimizing repeated parts, while C language pays more attention to the explicit declaration of variables.

In addition, there are some differences between Go language and C language in terms of function definition and calling.

In Go language, the keyword of function definition is func, and the function can directly return multiple values, as shown below:

func add(a, b int) (int, int) {
    return a + b, a - b
}

And in C language, The syntax of function definition is relatively cumbersome, and you need to specify the return type and parameter type, as shown below:

int add(int a, int b) {
    return a + b;
}

In addition, there are some differences between Go language and C language in terms of control flow statements.

In the Go language, the conditional expression of the if statement does not need to be bracketed, as shown below:

if a < 10 {
    // do something
}

And in the C language, ifThe conditional expression of the statement needs to be added with parentheses, as shown below:

if (a < 10) {
    // do something
}

In addition, there is no while loop in the Go language, but uses the for loop. Instead, for example:

for i := 0; i < 10; i++ {
    // do something
}

And in C language, a while loop is usually used to achieve a similar function, as follows:

int i = 0;
while (i < 10) {
    // do something
    i++;
}

In general, Go There are many similarities and differences in syntax between C language and C language. These differences are mainly reflected in variable declaration and assignment, function definition and calling, control flow statements, etc. Through the comparison in this article, readers can have a deeper understanding of the differences and commonalities between these two programming languages, and thus better grasp their grammatical features.
