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 :')

properly formatted the code
- I have a quick question, for the 'ptr( )' what does it mean here?
