Question

C programming ! - implement fgets instead scanf("%s",&new_node->car_name); into my program.

Source code:

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

struct node

char car_name[20];
char type;

{
struct node* new_node=(struct node*)malloc(sizeof(struct node));

int year;
float val,saleprice;

printf(" Enter car name: ");
scanf("%s",&new_node->car_name);

printf("Enter car type: ");
scanf(" %c",&new_node->type);

return;
}

void deleteCar(struct node**head_ref)
{

printf(" Enter car name: ");
scanf("%s",&name);

struct node *temp=*head_ref,*prev;
