Error Detection and Correction
Hi,
I am making an application for "The Hamming Code". I am having some problems I don't understand how to do this. The user can only put up to 5 characters. then the user will put the bit to flip.the output should look something like this:
Code:
Input a word to transmit: B <enter>
Input a bit to flip: 12 <enter>
Processing…
- Transmitting character "B" with binary code 0100 0010
- The parity bits are:
Bit 1 2 4 8
1 1 1 0
- The encoded array is:
Bit 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
1 1 0 0 1 0 0 0 0 0 1 0 0 0 0
Sending….
It is being corrupted by flipping bit 9.
- The corrupted array is:
Bit 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
1 1 0 0 1 0 0 0 0 0 1 1 0 0 0
The corrupted character at destination is "C"
The checksum for parity bits is:
Bit 1 2 4 8
1 1 0 0
The corrected character is "B"
I can read the chracter and convert it to binary but I am stuck afterwards.
Code:
#include <stdio.h>
char ascitobinary();
int main(void){
ascitobinary();
}
char ascitobinary(){
char x ;
int y;
printf("Input a word to transmit: " );
scanf("%c",&x);
for(y = 0; y < sizeof(char) * 15; y++)
printf("%c ", ( x & (1 << y) ) ? '1' : '0' );
puts("");
return 0;
}
Thanks alot for help.
