I want to assign input_x to an array. For example:
I have 8 sensors and I'll use b port on 18f4550 for reading their values 1 or 0.
I declare an array int array[8] in which I don't describe the values,
then I'm going to do array=input_b.
But it doesn't work. It says it needs an LVALUE.
Please, is it possible or not? If it is, where am I doing a mistake?
Thank you.

OK. It is not very clear from your description, but I suspect you want to have an array of single bits containing the values from a port?.
If so, answer depends on the age of your compiler.
Code:
union {
int8 b;
int1 bits[8];
} port_bits;
port_bits.b=input_b();
//then port_bits.bits[0] to port_bits.bits[7] are the eight bits from the port
This is only supported on reasonably 'recent' compilers.
