I've got a website with the install function, and the install want the safe_mode to be off but my web hosting company wouldnt turn safe modee off, is der a way to get around this?
> scanf( "%d",year); You need &, as in scanf( "%d", &year); You should also start using a compiler which will warn you about printf / scanf format string errors before you get to run your code and have it fail in a variety of interesting ways. gcc -W -Wall -ansi -pedantic -O2 prog.c is usually a revelation the first time you try it
This is my code.
if (r <=-.9)
{
printf("Data are linearly correlated: r = %1.3f\n",r);
printf("What year do you want to predict? ");
scanf( "%d",year);
predict = a + b*year;
printf("Predicted index in year %d is %lf", &year, predict);
}
else if (r >-.9)
{
printf("Data are not linearly correlated: r = %1.3lf\n",r);
printf("Stopping");
}
This is the output that i get
Data are linearly correlated: r = -0.985 What year do you want to predict? 2010 predicted index in year 2293448 is -6710792614
The problem is when i re print 2010 the output it 2293448.

int year;
if (r <=-.9){
printf("Data are linearly correlated: r = %1.3f\n",r);
printf("What year do you want to predict? ");
scanf( "%d",year);
predict = meany + b*year;
printf("Predicted index in year %d", year);
}
In the below code im getting a year from the user. but when I print of the year from scanf is doesnt print the correct value such as 2010 will be printed as 74.43434 (somthing like this). If i change the scanf from %.3lf to %f or %d the program will crash.
ANY IDEAS ANYONE?
double year;
if (r <=-.9){
printf("Data are linearly correlated: r = %1.3f\n",r);
printf("What year do you want to predict? ");
scanf( "%.3lf",year);
predict = meany + b*year;
printf("Predicted index in year %.3lf is %lf", year, predict);
}
else
printf("Data are not linearly correlated: r = %lf\n",r);
printf("Stopping");
void print(int x, int y)
{
cout << x << " " << y << "\n";

void calculate( int* meanx, int* meany)
// The two parameters are pointers to the integers that
// are declared in main()
{
*meanx = 1;

}
int main()
{
int meanx = 0;
int meany = 0;
calculate(&meanx, &meany);
print(meanx, meany);

Can u show me in this code, I still didnt quet grasp it.

You wouldnt be able to find a book to cover the whole Internet for you. Every single programing language that you know of and every single server that you know of is connected to the Internet. So you'll need so start from how to create simple website (XHTML, CSS), then get into getting that site to do something (ASP.NET, PHP, JavaScripts), then you want info from that site to be stored in a Database (SQL, postgrass) once you got a site that is working then you get into hosting it on the Internet. You also need to know about networking and how IPs and DNS works. Its such a broad topic that it's impossible to cover in one go.
Im running xampp as a testing environtment and want to be able to show it to some clients. Is it possible to use xampp as my server and access it via my DNS?
Im sitting behind a NAT router? I've done the static LAN IP and forwarded port 80 to my computer on the router.
Try this admin tool, it has lots of tools within. You can test pretty mush all hardware. http://www.mininova.org/tor/435381 But you need a torrent client.
You can do a repare with the burnt XP cd. Just select repare at the first option when it asks you, dont repare on the second option otherwise you'll be installing XP again with the burnt CD. Also check your HDD, monitor your temp so it doesnt get too hot. Check ur RAM and motherboard.
I'd say the documents are kept on the serve only unless you have enabled offline files option. If your using AD for user to login then you dont need to worry about the PC, because AD will redirect the users to there home directory(my documents) where ever in the network they login.
But use the xp CD to repair the installation (if it reboots constantly) Test you HDD and memory and if you can also the motherboard (there are admin tools you can d/l and use that to test your hardware).
as Im reading I want to be able to count how many rows I've read and also add the all values as im reading from the second column, could some help plz This is the code
#include <stdio.h>
#include <stdlib.h>
struct data{
int x;
int y;
};
void read_info(void);
int main()
{
read_info();
}
void read_info(void)
{
FILE *stocks;
struct data stock;
int x;
char buf[80];
int total = 0;
int numberofrecords = 0;
stocks = fopen("banana.dat", "r");
if(stocks==NULL)
{
puts("No data in file");
return;
}
while (fgets(buf, 80, stocks) != NULL && !feof(stocks))
{
sscanf(buf, "%d %d", &stock.x, &stock.y);
printf("n1 = %d n2 = %d\n", stock.x, stock.y);
/*numberofrecords = stock.x++;
total += stock.y;
printf("%d %d", numberofrecords, total);*/
}
fclose(stocks);
}
