Answer:
from socket import *
hostname = input('Enter the host to be scanned: ')
ip_add = gethostbyname(hostname)
connections = [ ]
for i in range(133, 136):
s = socket(AF_INET, SOCK_STREAM)
conn = s.connect_ex((ip_add, i))
print(conn)
connections.append(conn)
if 0 in connections:
print ('Host is online')
s.close()
else:
print ('system is unreachable')
Explanation:
The python source code above scans for all the available range of ports in the provided hostname, if any port is available, the host is online else the program print the error message "system is unreachable.

Answer:
// CPP program to Convert characters
// of a string to opposite case
#include<iostream>
using namespace std;
// Function to convert characters
// of a string to opposite case
void convertOpposite(string &str)
{
int ln = str.length();
// Conversion according to ASCII values
for (int i=0; i<ln; i++)
{
if (str[i]>='a' && str[i]<='z')
//Convert lowercase to uppercase
str[i] = str[i] - 32;
else if(str[i]>='A' && str[i]<='Z')
//Convert uppercase to lowercase
str[i] = str[i] + 32;
}
}
// Driver function
int main()
{
string str = "GeEkSfOrGeEkS";
// Calling the Function
convertOpposite(str);
cout << str;
return 0;
}
