pointers to Enum in C

[askcq]

#include <string.h>
enum State {yes=1, no=0}SS, *ptr;
struct Example {
enum State *ptr;
}EX;
 
enum State SS=yes;
main()
{
struct Example* PTR;
//enum State *ptr;
PTR=&EX;
ptr=&SS;
printf("%d",PTR->ptr);
}
 

no errors ....but unable to print the enum values for "yes" and "no"
Is the logic incorect

You've written 'enum' a few too many times; you only need it once to declare a new variable type:

#include <string.h>
enum State {yes=1, no=0} SS, *ptr;
// Now State type is declared
struct Example {
 State *ptr;
 // ptr is a pointer to a State
 } EX;
State SS=yes;
// SS is a variable of type State
 

[EDIT: Actually, this applies only to C++, not C as you have indicated. Ignore this post]

Isn't it just that you should write PTR->ptr=&SS; on line 13?

no its not working
pls help

Avoid defining multiple things on one line. Separate the emum from the variables:

enum State {yes=1, no=0};
State SS = yes;
State*ptr;
 

Next, when you create yout struct variable, you never initialize the pointer in the variable:
That is, EX.ptr is never pointed at a State variable.

Try this out and let me know what happens.
