OUTPUT

Enter the length of data stream: 10

Enter the data stream 1 1 0 1 0 1 1 1 0 1

Number of 1's are 7

Enter the choice to implement parity bit

1-Sender side

2-Receiver side

1

The data stream after adding parity bit is

11010111011

Enter the length of data stream: 10

Enter the data stream 1 1 1 1 1 0 0 0 1 0

Number of 1's are 6

Enter the choice to implement parity bit

1-Sender side

2-Receiver side

2

There is no error in the received data stream
