Answer:
The receiver will not detect the error.
Explanation:
The byte sent by transmitter: 10101010
The byte received by receiver due to channel noise: 10011010
If you see the bold part of the both sent and received bytes you can see that the number of bits changed is 2.
The two communicating devices are using a single-bit even parity check. Here there are two changed bits so this error will not be detected as this single bit even parity check scheme has a limit and it detects the error when the value of changed bit is odd but here it is even.
This parity scheme basically works well with the odd number of bit errors.
Answer:
// program in C++.
// headres
#include <bits/stdc++.h>
using namespace std;
// main function
int main()
{
// array
int temperatures[7];
// count variable
int count=0;
cout<<"Enter the temperature of all days:";
for(int a=0;a<7;a++)
{
// read temperature of 7 days
cin>>temperatures[a];
// find temperature is extreme or not
if(temperatures[a]<-10||temperatures[a]>25)
// count
count++;
}
// print count of extreme temperature
cout<<"number of days of extreme temperature:"<<count<<endl;
return 0;
}
Explanation:
Create an array of size 7 to store the temperature of all days of week.Read the temperature of each day.If the temperature is less than -10 or greater than 25 then increment the count.This will count the number of days of extreme temperature.Print the count.
Output:
Enter the temperature of all days:-20 12 18 30 32 -15 15
number of days of extreme temperature:4
