Indian guy? has to be awesome tutorial, thank you very much!!!

[MdAsif-eolm]

where is the code link bro?? u hv given tht nnsense job sites

[vladometov]

Thank you very much. You helped me a lot.

I don't understand what is use of array a[].actually main program start at point where u receiving 7 bit code is it true??
Give reply fast pls

[anupmallah]

I think its a wrong code because the first and second array are not related to each other @Thecodersbay pls reply?

[debug]

the 2 arrays ( a[ ] and b[ ] ) should be related, where the Generated and Received codes are related?

Yaar teri website me kahi bhi koi code nahi hai

#include<iostream>

using namespace std;

int main() {
int a[10];
int b[10], c, c1, c2, c3, i;

cout<<"Enter 4 bits of data one by one\n";
cin>>a[0];
cin>>a[1];
cin>>a[2];
cin>>a[4];

//Calculation of even parity
a[6]=a[0]^a[2]^a[4];
a[5]=a[0]^a[1]^a[4];
a[3]=a[0]^a[1]^a[2];

cout<<"\nHamming code is:\n";
for(i=0;i<7;i++)
cout<<a[i];

cout<<"\n\nEnter received a bits one by one\n";
for(i=0;i<7;i++)
cin>>b[i];

c1=b[6]^b[4]^b[2]^b[0];
c2=b[5]^b[4]^b[1]^b[0];
c3=b[3]^b[2]^b[1]^b[0];

c=c3*4+c2*2+c1 ;

if(c==0) {
cout<<"\nNo error while transmission of data\n";
}

cout<<"\nCorrect message is\n";

//if errorneous bit is 0 we complement it else vice versa

b[7-c]=1;
else
b[7-c]=0;
for (i=0;i<7;i++) {
