Pointers to an array
PostPosted: Wed Sep 29, 2004 7:58 am     Reply with quote

when I pass an array to a function
func(array);

I the any difference if I get it in the function that way:
void func(*array[])

or this: void func(*array)

in other words, is there any defference whether I use the square brackets or not?
Thank you

When you have this type of question, you should make a test program,
compile it, and look at the .LST file.

For example, here is a test program for your question.
Compile it and look at the .LST file.

Code:
#include <16F877.H>
#fuses XT, NOWDT, NOPROTECT, BROWNOUT, PUT, NOLVP
#use delay(clock = 4000000)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7, ERRORS)

void func1(char *array[])
{
char c;
c = array[0];
}
 
//------------------------
void func2(char *array)
{
char c;
c = array[0];
}

//==================================
void main()
{
char array[10];

func1(array);

func2(array);

while(1);
}
