Question

Consider this code segment:

char message[255];
char newMessage[255];
int i;
for (i = 0 ; i < 255 ; i++)
     message[i] = i;
newMessage = message;

When I try to do this I get for the last line an error:

incompatible types when assigning to type ‘char[255]’ from type ‘char *

Why do I get that if the arrays has the same type? How do I fix it?

Thanks in advance

Answer 1

One way to fix this is by declaring newMessage as a pointer: char* newMessage.

Another is by using memcpy() — or strncpy() if message is a string — to copy the contents of message into newMessage.

Which method is preferable depends on what you then do with newMessage.
