Incompatible types in assignment

[billiabon]

Hello,everybody ! I need your help! My problem is this assignment

[CODE=c]char pnm[10];
void enqueue(int pd,char pnm[10],int pnum,int ptm,struct queue *z)

{struct node *p;

p=(struct node *)malloc(sizeof (struct node)); // give me memory such big

p->id = pd;

p->name = pnm; here is "incompatib le types in assignment" for the gcc

p->num_quant=pnum ; [/CODE]


Which is the appropiate assignment? Why?

What type is p->name? Are you sure don't mean to copy the array contents instead of it's address?

Thanks for your answer! With the assignment
p->name = pnm; i want to copy the content of array pnm to the field "name" of the structure node which the pointer p points. I don't want to copy any address

But how can u copy an entire array in one field?
Dont you think your field should also be an array;
whenever an incompatible erreor is coming ; it mens your assigning something wrong; other than expected to a variable.
And its quite obvious that you cant store an entire array in single variable!

Hello! You're right but if the field is a char array 10 bytes long and the pnm is char array 10 bytes long then why the problem occurs?

The "=" doesn't copy array contents it just tries to copy the element you give it (in this case the array start address)

You will have to use a function such as strncpy() or memcpy() or something to actually copy the contents from one array to another.
