many push button (10 push button) with PIC16F877A

[john120]

I want to implement a circuit made by a PIC16F877A which is interfaced to 10 push buttons ;when one button is pressed the others can not be activated.
and each push button correspond to a digits which is displayed on the 7segment display.
So this button correspond to each number which is displayed on the 7segment.

How can I proceed,I am proposing to use switch case;can you plz help me with CCS C Compiler in ccs c compiler.

Thanks
