Hi, I got a problem in reading and write on file.
I have to create an virtual agenda, therefore I enter a name and a number for N persons.
After entering the infos if the file doesn't exist, the program create it and save the infos, if the file exist the program will overwrite all the lines.
But when i write on screen the information from a fprintf the lines are messed up.
I load the infos form the file with this:
fp=fopen("agenda.txt","r");
if(fp)
{
rewind(fp);
while(!feof(fp))
{
fscanf(fp,"%s %s",inome,inum);
if(ii==NULL)
{
head=malloc(sizeof(agenda));
if(!head)
{
printf("Memory Problems");
exit(1);
}
head->prev=NULL;
head->next=NULL;
strcpy(head->nome,inome);
strcpy(head->num,inum);
ii=head;
fflush(stdin);
}
And i save the info from the memory to the file with this
void save()
{
fp=fopen("agenda.txt","w");
ptr ii=head;
rewind(fp);
while(ii)
{
fprintf(fp,"%s %s",ii->nome,ii->num);
ii=ii->next;
}
fclose(fp);
return;
}
This is what happens after that the program writes on screen the infos from the file
