C Programming: Understanding Infinite Loops and Key Input Handling

The given code is a main function that runs an infinite loop. \u000d\u000a\u000d\u000aIn each iteration of the loop, it calls the functions display() and keyscan(). \u000d\u000a\u000d\u000aAfter that, it checks the condition if K1, K2, or K3 is pressed (value is 0). If any of these keys is pressed, it sets the value of FMQ to 0. Otherwise, it sets the value of FMQ to 1. \u000d\u000a\u000d\u000aThis loop will continue running indefinitely, continuously updating the display and scanning for key inputs. The value of FMQ will be updated based on the key inputs.
