Hard mode: nothing that ends in "ville".

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...

Like Jim said, %d is used with integers. Use %f in the final two printf statements, since cir and area are of the type float.

Let's talk about pi now. First of all, 3.14 is not an integer. It is a...

That worked, thanks.

scanf("%[^\n]", s->name) does the same thing.

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.

...

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

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

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

The Windows equivalent of that command is


find /V "(ROM_LOAD|ROM_REGION)" your_sourcefile.c

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);...

if (mysql_real_connect (conn, opt_host_name, opt_user_name, opt_password, opt_db_name, opt_port_num, opt_socket_name, opt_flags) == NULL)

Well there's your problem. You're not giving it a host...

Some psuedocode:


int main(int argc, char *argv[])

if argv[1] is null, printf usage message

argv[1] will be file to be copied

FILE *in = fopen argv[1], mode "r"

Do you have to set up a web server like Apache on localhost first? If so, make sure it's set up properly.

Thanks for all the explanations. I'm starting to understand it better.

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...

The double data type is usually eight bytes.

Try chdir, or opendir if chdir isn't available. chdir will return -1 if the specified directory doesn't exist. opendir will return NULL if the specified directory doesn't exist.

Also, you can use...

CommonTater is in the lead.

Whoever writes the fanciest program gets a cookie.

Post the code or quit asking for help.

unsigned int iseed = (unsigned int)time(NULL);
srand(iseed);

You don't need a variable for time(NULL). Just replace that with srand(time(NULL));. That while loop is completely unnecessary....

The C Board is not a homework machine.

Try writing the code yourself, and we'll tell you what's wrong with it.

a. The odds of it being EOF are incredibly slim, and b. Why doesn't he just assign it to 0?

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

And your main function should look like this:


int main(void) {
//...

Just curious, why wouldn't your compiler include string.h? It's apart of the standard C library, and all of those headers should be installed by default.

Take out the scanf statement, and assign data to getchar() inside the while conditional.


#include <stdio.h>

int main(void) {
int data;
while ((data = getchar()) != EOF)
...
