seriously, your gettin syntax errors left and right, I would fix those before worrying about thos function calls getting messed up.

$10 says fixing those syntax errors will also solve your other problems!



i fixed the syntax errors before and it didnt help, its definitly the function call problems. i will finish the syntax erors for you now though.
Michael19
i fixed all the syntax errors in the original post now i think.

wtf's this then?

for (i=1; i

{

min_pos = i;

for (j=i+1; j
Michael19
for (i=1; i < n; i++)
{
min_pos = i;
for (j=i+1; j < n; j++)




is that right?:conf: i cant notice the mistake if your post in the original one.

i aint be doing this very long so that why its e. :stongue:

when i go to edit it, its fine, but it doesnt look fine when posted, n piece of
Michael19
there
Resnick
so where is this getline function actually defined? u gotta include it at the top of ur code (unless its standard built in functino of c, but make sure ur including the right files, and using right parameters/syntax to call the function)

spot on, cheers

PHP:




second problem is " too few parameters in call to strtod(const char*, char**0"


any ideas anyone?:conf:

Resnick
double strtod(const char *nptr, char **endptr);

im not even sure if thats what ur talking about..but google says theres two parameters :P

edit: and in fact thats what the compiler error told u...ur only giving it one parameter in the code u quoted
