Can formal parameters in C language be empty?

In C language, the formal parameters of a function can be empty, that is, a parameterless function. The characteristics of parameterless functions include being concise and easy to read and easy to write, but they have poor flexibility and reusability and are only suitable for specific situations, such as writing utility functions or initialization functions.

Whether formal parameters in C language can be empty

Answer: Yes, Can be empty.

Detailed explanation:

In C language, the formal parameters of a function can be empty, that is, the function can have no formal parameters. This is called a parameterless function.

Example:

<code class="c">void no_args() {
  // 无需任何参数
}</code>

Advantages:

##The parameterless function is more concise and easier to read.
• Parameterless functions are easier to write and understand because there are no parameters to deal with.

Disadvantages:

Parameterless functions are less flexible and reusable because the behavior of the function cannot be adjusted based on different inputs.

Note:

• Parameterless functions are only suitable for certain situations, such as writing simple utility functions or initialization functions.
