# Question: im having trouble creating the following function in c use...

###### Question details

I'm having trouble creating the following function in C:

Use the following struct node and create the following function:

int get_node(struct node*);

which searches for the first node where valid=0.

Return that index, or if no such node is found, return -1.

Struct node:

struct node {
int data;
int next;
int valid;
};
