Only Change One Bit.
In Gray code, there is only one bit location different between numeric increments, which makes mechanical transitions from one digit to the next less error prone. The following chart shows normal binary representations from 1 to 10 and the corresponding Gray code.

Can you please give more explanation for converting Binary code to Gray code ?

Decimal 7 = 0111 binary.
0+1+1+1.
MSB 0 1 0 0 (add without carry).
Ans = 0100.
0+1+1+1.
MSB 0 1 0 0 (add without carry).
Ans = 0100.

Decimal 7 = 0111 binary.
Copy the 1st bit i.e. in 0111. The 1st bit is "0".
Then do the x-OR operation for bits 0111 = 0100.
x-OR = (0&1=1 and 1&1=0).

Binary code for 7 is ---0111.
Gray code will be done by xor on 0111 where in xor-- ( 01--1, 10 -- 1, 00--0, 11--0).
To get Gray code add from left to right i.e
1 xor 1 ---0.
1 xor 1 --0.
1 xor 0 --1.
Last digit 0 write as it is, so the answer is 0100.
