Remove clutter and try to come up with a better title
  • Regarding ' ptr( ); 'in this code & what does it mean?
  • What does a variable followed by parentheses ("ptr()") mean?
  • I have a quick question, for the 'ptr( )' what does it mean here?
  • ```c
  • #include<stdio.h>
  • #include<stdlib.h>
  • void PrintHello()
  • {
  • printf("Hello\n");
  • }
  • int Add(int a, int b)
  • {
  • return a+b;
  • }
  • int main ()
  • {
  • void (*ptr)();
  • ptr = PrintHello;
  • ptr(); //For this specific line of code, what does it mean?
  • }
  • ```
  • Apologies for the format of my question as I'm still trying to understand how to actually use Codidact :')

 #include<stdio.h>

 #include<stdlib.h>

 void PrintHello()

{

    printf("Hello\n"); 
}

int Add(int a, int b)

{

    return a+b;
}

int main ()

{

    'void (*ptr)();

    ptr = PrintHello;
 
    ptr(); //For this specific line of code, what does it mean?
}
