To read switch from PORTA and RB0 as input and RB1-RB7 as outputs

If switch is connected to PORTA.F0 then


Code: 
void main() {

TRISA = 0b00000001; // set PORTA pin RA0 as input all others as output
PORTA = 0x00;          // clear PORTA
TRISB = 0b00000001; // set RB0 as input, RB1 - RB7 as outputs
PORTB = 0x00;          // clear PORTB 
 
while(1) {

if (PORTA.F0 = 1) {
        // do something
}

}


}

what is the meaning for this

"if (oldstate && Button(&PORTB, 0, 1, 0)) " and what is the "&"
represents here.

similarly "if (Button(&PORTB, 0, 1, 1))"
 

There is a double "&&" logical AND operator and a single "&" bitwise AND operator, both are binary operators requiring two operands.

The following is a logical AND operator:

Code: 
if (oldstate [COLOR="#FF0000"]&&[/COLOR] Button(&PORTB, 0, 1, 0))



However, in the case of the following:

Code: 
if (Button([COLOR="#FF0000"]&[/COLOR]PORTB, 0, 1, 1))

It is a single "&" "address of" operator in front of PORTB, a unary operator requiring a single operand.

Which returns the address of storage used for the variable PORTB.

I CAN'T UNDERSTAND. I NEED MORE DETAILS...PLEASE
 

Check this tutorial for learning C language.
https://www.cprogramming.com/tutorial/c/lesson6.html
The single "&" sign before a variable indicates that you try to the "Address Of" the value in the memory, not the value stored in this variable.
Code: 
For example:
Suppose we have an integer variable called "X" carrying the value "0xAA" and its location in the memory is "0xFE"
printf("Value of X = %d", X);  ---> Prints the "0xAA"
printf("Location of X = %d", &X);   ---> Prints the "0xFE"

Hope it is clear now.
