    Think about this. printf, sprintf, and fprintf all work on streams, right? Just like scanf, sscanf, and fscanf work on streams?

    When I use a function like rewind() or fseek() with SEEK_END, it...

  6. [SOLVED] fgets is skipping the second time I call it

    Hey C Board. I created a typedef structure called Student, and I want to pass this structure to two functions, getStudent, to scanf all the members, and printStudent, to print all the members.

    ...
  7. Ok, C Board, what am I doing wrong? (Linked lists)

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

    typedef struct node {
    int value;
    struct node *next;
    } block;

    int main(void) {
    block *root = NULL;

    Just a suggestion, even though your program technically works like it's supposed to. Make i an integer, use while (i != 8) for the while condition, and replace the two getchars with scanf("%d", &i);...

    I'm an experienced C programmer, but I don't know that much about C++ and I'd like to know why it's better, worse, or just as good.

    I'm probably just ignorant, but to me, I don't see that many...

    Maybe this wouldn't work in this case, but I've always used fgets(str, sizeof(str), stdin) to get strings from stdin.
