struct node * void expected identifier or '(' before 'void'

Advertisements

There is a function like this. I took this error expected identifier or ‘(‘ before ‘void’
How to solve this problem? Thank you.

struct node * void ekleSirali(struct node * r,int x){
     if(r==NULL){
        r=(struct node *)malloc(sizeof(struct node));
        r->next=NULL;
        r->x =x;     
        return r;  
     }

I don’t know whether I should write struct.

>Solution :

The type specifier void is redundant and invalid in this context. Write

struct node * ekleSirali(struct node * r,int x){

That is the function return type can be either void (if the function returns nothing) or struct node * (if the function returns a pointer of the type struct node * as shown in your code snippet).
