problem with array

[mickey]

Hi I need to do this but I haven't problem with array (don't compile):


GLfloat position[4];
GLfloat[] getPosition() {return &position[0]; }

How can I do this? Thanks

There are two solutions:
GLfloat[4] getPosition() {return position; }
or more efficient and more dangerous:
GLfloat * getPosition() {return &position[0]; }
// or
// GLfloat * getPosition() {return position; }

Sorry, your firset solution (I didn't try the second because I don't need a pointer value) give me this error:


C:\Qt\3.2.0Educational\include\qsignalslotimp.h(66 ): fatal error C1903: unable to recover from previous error(s); stopping compilation

unable to recover from previous error(s); stopping compilation
What is the first error?

Sorry, your firset solution (I didn't try the second because I don't need a pointer value)...


int arr[4] = {0, 1, 2, 3};
int *arrPtr = arr;
printf("%d\n", arrPtr[2]);
Guess what it prints...

There isn't first error..There are many errors after like those:


error C2061: syntax error : identifier 'getPosition'
error C3400: 'string': unexpected token/character encountered in attribute block
error C2334: unexpected token(s) preceding '{'; skipping apparent function body

There isn't first error..
That's quite interesting ;)

You will have to use one of these:

GLfloat * getPosition() {return &position[0]; }
// or
GLfloat * getPosition() {return position; }

OK. those solution are write. I wondered how I must code the first solution with [].
Thanks
