Will this code work propertly?

I have 4 switches and 4 LEDs. I want to turn off the first LED with the first switch, the second one with the second switch, and so on. When I turn off the switch, LED should turn on. All switches connected to PORTA, all LEDs to PORTB. Initially, all LEDs are on. Will this code do the job?
Code:
PORTB=0b00001111;
   
    if (PINA & (1<<n))
    {
        PORTB = PORTB & ~(1 << n)
    }
    else
    {
        PORTB = PORTB | (1 << n);
    }

It will work if,
The TRIS registers are setup correctly.
Pullup resistors are on port A or the internal pullups are on. And, the switch connects the port pin to GND.
Analogue is turned off.
Anything else (osc etc.) required is setup correctly.

This is the way all four switches and LEDs are connected.
