New to OS X, why wont this work?

Ok, here is the first program:

 

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

int main(int argc, char *argv[])
{
 char name[64];
 printf("Please enter your name: ");
 fgets(name, 64, stdin);
 name[strlen(name)-1] = 0;
 printf("Hello, %s!\n", name);
 exit(0);
}

 

Works fine on my computer, but my friend gets "Bus error".

 

He has Tiger on an intel mac, I have Leopard, but I doubt that should make a difference, it would be crazy if it did.

 

Second:

 

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

int main(int argc, char *argv[])
{
 FILE *fp;
 fp = fopen("testfile.txt", "w");
 fclose(fp);
 exit(0);
}

 

If I run it in terminal with the command ./programname it works fine, it creates a new file. But if I double click the program it only brings up terminal and finishes without making the file.

 

This just seen completely wacky. What's up?

1) The operating system does make a difference. Chances are you built it for the default 10.5 SDK, and not the 10.4 SDK. Go to Project -> Edit Project Settings, and look under the General tab.

 

2) When you double click the program — or even if you run it manually through terminal — it treats the current directory (pwd in terminal) as the working directory, so your file is created there. By changing directories (cd) into programname's path and doing ./programname, you change the current working directory.
