problems using memcpy

[newby01]

hey, i have a problem trying to figure out what i'm doing wrong with memcpy,

i get the following to errrors when i try to run this code.

a4.c:222: error: incompatible type for argument 1 of `memcpy'
a4.c:222: error: incompatible type for argument 2 of `memcpy'

memArray is an array of memRec structures.

for(i=foundIndex; i<memLoc; i++) {
 memcpy(memArray[i],memArray[i+1],sizeof(memRec));
 }

Could someone please tell me why my first and second arguments are incompatible types for memcpy and what they should be instead.

Thanx a heap

You need the address of the memArray[i], not the memArray[i] itself.

Assuming you have an array like this:

char str[100];

str[1] is just a single char, not a char*

(str + 1) is a char* because it takes the address of the first element of str and adds 1 to the pointer address, creating a new address.

&str[1] is the address of the 2nd char in the array, so it's also a char*
