Can an someone show me how to write a program which:
(i) Has 4 inputs of 5V on 4 different pins(Let's say PORTA),with switches on all of them.
(ii)The input control's 4 outputs(Let's say PORTB)
(ii)the output toggle each time a 5V is connected.(press switch once=1,press switch 2nd time=0)

you just need to toggle outputs with push buttons?

the input should be in high state always (works like our car remote)

Explain more accurately how the switches are connected.

The schematic diagram is as follow:

**broken link removed**

where p1.0,1.1,1.2,1.3 and p3.0 are the output pins(Lets say PORTA of the MCU). While for the input, i plan to use a 5V connected to 4 inputs(Lets say PORTB),between them there are pushbuttons.

A high state, 1 on the input will turn on p1.0 and p3.0 when the pushbutton is pushed once. The second push will turn on p3.0 but p1.0 will be turned on. The same goes with 3 other inputs, each is designed to turn on p1.1,1.2 and 1.3.

No, that link leads to a 'sign in' page.
