Thread: Once again I am wrong

Well I see a blatant one. Are you missing a semi-colon.

/edit
Why is *cptr, and i global and in display?

That should get you started!

Look a your errors when you try to compile they will help you out!

I am sure my problem is transferring the array from main to the display function,

You've declared *cptr, and i as global variables. Sounds to me like you don't really want that!

Okay that clears up most of my issues, but now I have a new one.

Code:

#include <stdio.h>

int *cptr, i;
int channel[7];

int display (int);

int main()
{
cptr = channel;
channel[7]={2,4,5,7,9,11,13};
display (cptr);

return 0;
}

int display (int cptr)
{
int i;
for (i=0; i<=6; ++i)
printf ("\nElement %d is %d", i,(cptr + i));

system ("Pause");

return 0;
}

the compiler tells me there is an error before the { in line 11. I can not for the life of me figure out what it is. I have been looking at my references and it looks correct to me. Can anyone else see what my noob eyes are missing?

channel[7]={2,4,5,7,9,11,13};
The initialization should be there the variable is defined. You cannot initialize array in that way afterwards

Code:

int display (int *cptr)
{
int i;
for (i=0; i<=6; ++i)
printf ("\nElement %d is %d", i,*(cptr + i));

system ("Pause");

return 0;
}

Code:

channel[7]={2,4,5,7,8,11,13};

Code:

channel[7]="2,4,5,7,8,11,13"

The change allouded the code to complile, the result was not that you wanted it to be. It would have to do with you at decaring that the channel[7] array at row 1, column 6 is 2,4,5,7,8,11,13. So you are not declaring you string for the array but your string for a single memlocation.

it means that you trying to assign something like:

Code:

int* p = NULL;
int a = p;

and in most cases it is wrong thing to do - there can be even not enough space in the int to store the value stored in the pointer... And Moreover, I don't think it is want you actually want to do... So you should pay a special attention to all this warnings to undestand what you are doing wrong
