Linker List stuck! even before entering

[ncode]

I try to do something called linked list but just before i dive in i'm stuck. Plz help

#include <stdio.h>
#include <stdlib.h>

struct node{	//Struct node type
	int data;
	struct node *ptr;
};

typedef struct node Node;

	Node newPtr;
	Node *sPtr=NULL;


int InsNewAtFirst(int value);//Function Prototype

int main(){
	

	
	InsNewAtFirst(100);
	InsNewAtFirst(50);
	InsNewAtFirst(150);
	InsNewAtFirst(450);
	InsNewAtFirst(5150);
	getchar();
}

int InsNewAtFirst(int value){
	
	newPtr=malloc(sizeof(Node)); //stuck!  cannot convert 'void*' to 'Node'
};

You defined the variable newPtr as "Node", which is not a pointer, hence the compiler message.

[ncode]

so how to fix it? I need newPtr as Node to being use as a node to store a data and a pointer.

You defined newPrt as a static variable: the memory for it is already allocated. So either this is what you want and it's not a pointer, or you do want a pointer and you need to declare it as such (like you've done for sPtr).
To sum up (and simplify) the memory for every variable you declare is already allocated for you, except if you declare it with as a pointer (*), in which case you need to allocate it manually. If you apply this rule, you see that what you've done is incorrect.

For linked lists you almost certainly want to use pointers, and I think that's what you intended since you called malloc. So:

    Node *newPtr;
