Can comment statements only be placed after one statement in a C program?

No, in a C program, a comment statement can be located after a statement, or at the beginning or middle of a line. Comment statements are used to add explanations and explanations to programmers. They will not be executed by the compiler, so they can be placed anywhere. Comment statements will not be executed by the compiler, so regardless of the position of the comment, it will not affect the running results of the program. Reasonable use of comments can improve the readability and maintainability of code and help other programmers better understand the intent of the code.

In a C program, a comment statement can be located after a statement, or at the beginning or middle of a line. Comment statements are used to add explanations and explanations to programmers. They will not be executed by the compiler, so they can be placed anywhere.

Comments in C language come in two forms: single-line comments and multi-line comments. Single-line comments start with two slashes (//), and multi-line comments start with /* and end with */.

Adding comments after a statement is the most common usage. For example:

int a = 10; // 定义一个整型变量a并赋值为10

Such comments can provide an explanation of the statement in the code, helping other programmers understand the intent of the code.

In addition to adding comments after statements, we can also add comments at the beginning or middle of a line. For example:

// 这是一个简单的C程序
#include <stdio.h> // 包含标准输入输出头文件
int main() {
    int a = 10; // 定义一个整型变量a并赋值为10
    printf("a的值是：%d\n", a); // 打印a的值
    return 0;
}

In this example, we have added comments at different places in the code to provide explanation and explanation of the code. Doing so can help other programmers better understand the code, especially when dealing with complex logic or algorithms.

It should be noted that the comment statement will not be executed by the compiler, so regardless of the position of the comment, it will not affect the running results of the program. However, good commenting habits can improve the readability and maintainability of your code, making it easier to understand and modify.

Summary

In a C program, a comment statement can be located after a statement, or at the beginning or middle of a line. Reasonable use of comments can improve the readability and maintainability of code and help other programmers better understand the intent of the code.
