# A binary bar code scan is a bit pattern that contains only 1s and 0s.

1.   A binary bar code scan is a bit pattern that contains only 1s and 0s. Write a program that finds the edges of light and dark regions. Process an input bit pattern in the following manner:

Assign a 1 to the output bit pattern whenever two consecutive bits (one bit and it’s previous bit) are different

Assign a 0 to the output bit pattern whenever two consecutive bit (one bit and it’s previous bit) are the same

Assign 0 to the first output bit since there is no previous bit for the first bit  For example, input and output bit pattern of the program that detects the edges might look like the following:

Input: 00101101 Output: 00111011

2)  Assume the input contains exactly 8 bits.

3)  As part of the solution, write and call the function edge() with the prototype         void edge(int n, int a1[], int a2[]);

to perform edge detection. The arguments of the function edge() contain the length of the input and output arrays with the same size, the input array a1, and output array a2.
