Meaning of // in C

In C, double slashes (//) represent single-line comments .

Role

Comments can be used to add explanatory and descriptive information to the code so that it is easier to understand when other developers or yourself review the code in the future. Comments are not processed by the compiler and therefore do not affect the logic or execution of the program.

Syntax

Comments start with a double slash (//) and continue to the end of the line. Commented text will be ignored at compile time.

Example

<code class="cpp">// 这是单行注释
int main() {
  // 这是另一个单行注释
  return 0;
}</code>

Advantages

Using comments has the following advantages:

  • Improve the code Readability and maintainability
  • The purpose and implementation of documented code
  • Explanation of complex code segments
  • Mark unfinished or pending code
