#What are the methods of function calling in C language?

How to call functions in C language:

1. The most common is to call directly

void fun(void)
{
   ......
 //你的代码
   .....      
}
{
   .......
  fun();
    .....
 }

2.Use function pointer

void fun(void) 
{ 
    printf("OK!\n");
} 
int main(void) 
{ 
    void (*pfun)();    
    pfun=fun;
    (*pfun)();        
    return 0;
}

3. Function parameter method

void fun(void) 
{ 
    printf("OK!\n");
}  
{ 
    CallFun(fun);

In summary, there are three main methods of calling functions in C language: direct calling, function pointer calling, and function pointer passing calling. The latter two are essentially the same, but there are slight differences in whether there is a return value.
