linked lists
int mode=0,i=0;
char filename[15],readletter;
FILE *fptr;
struct data{
char artist[48];
char album[48];
char ref[16];
float cost;
int year;
struct data *next;
};
struct data *input,*start;
input->next=NULL;
start=input;
switch(mode)
{
case 1: /*Reading in data*/
printf("Enter the artist: ");
scanf("%s",&input->artist);
break;
can some please help with malloc settings
thanks

ok works now how do i?
lol my brain has had enough
ive been going at this c program allday
int mode=0,i=0;
char filename[15],readletter;
FILE *fptr;
struct data{
char artist[48];
char album[48];
char ref[16];
float cost;
int year;
struct data *next;
};
//struct data *input,*start;
//input->next=NULL;
//start=input;
struct data *input = ( struct data* )malloc( sizeof( data ) ),*start = input;
i changed that and it works thank you
case 1: /*Reading in data*/
printf("Enter the artist: ");
scanf("%s",input->artist); /*use fgets( ( *input ).artist, 48, stdin ); ( *input ).artist[strlen( ( *input ).artist ) - 1] = 0;*/
printf("/*what do i put here*/");
break;
i think its taking data in but what do i put in the printf to check
thx

memory writting error
VVV thx for your help so far
but now stuck on entering values
int mode=0,i=0;
char filename[15],readletter;
FILE *fptr;
struct data{
char artist[48];
char album[48];
char ref[16];
float cost;
int year;
struct data *next;
};
struct data *input=(struct data*)malloc(sizeof(data)),*start=input;
printf("\nEnter the artist: ");
scanf("%s",input->artist);
//fgets( ( *input ).artist, 48, stdin ); ( *input ).artist[strlen( ( *input ).artist ) - 1] = 0;
//printf("%s", (*input).artist);
//puts((*input).artist );
printf("Enter the album: ");
scanf("%s",input->album);
printf("Enter the reference: ");
scanf("%s",input->ref);
//printf("%s", (*input).ref);
printf("Enter the cost: ");
scanf("%f",input->cost);
printf("Enter the release year: ");
scanf("%d",input->year);
everything is fine until i get to the float
then i get a memory error
i can get round this by making it a char as well but i thought it would auto be a float?

thx again VVV
i now feel quite small
it was so simple i couldnt see it
