Sorry i'm newbie here and like to learn.I had a problem here can anyone give a code/solution for this problem:
Question:
Connect a DIP switch to port B and 7 segment(common Cathode) to port C.Write a program to read input from DIP switch connected to port B and display them on each segment of the 7 segment as show below:
DIP SWITCH 7 segment
0000 - all segments off
0001 - segment A on,others off
0010 - segment B on,others off
0011 - segment C on, others off
0100 - segment D on,others off
0101 - segment E on, others off
0110 - segment F on,others off
0111 - segment G on, others off
1000 - segment DP on,others off
1001 - all segment on

What hardware are you using?
Have you any code samples you could work from? Adapting existing code is a lot easier than writing code from scratch. For example, do you have example code to read from some ports and write to others? What's the background to this; are you learning on your own, or are you on a course? If you read the switches simultaneously you can treat the resulting value as a number and use switch logic, e.g. Code:
switch (read_DIP())
{
case 0: write_7seg(0); break;
case 1: write_7seg(1); break; // assumes segment A is at bit zero
case 2: write_7seg(2); break; // assumes segment B is at bit 1
