So I have a project that has 3 inputs (and there all buttons) and 3 output (lcd). So how can it detect the button getting pressed?

Have a look at the example programs that come with the Arduino IDE.

The digitalRead() instruction is used to detect whether the voltage on an I/O pin is HIGH or LOW

As stated above, you have the code already.

Do you have the Arduino IDE? Then you already have plenty of code. Look in Examples for Digital/Button or Debounce or StateChangeDetection. All detect buttons being pressed.
