TCL Interview Programs

Disclaimer – There are always multiple approaches to solve a problem. We have used only one out of those. You can try other logic based on your understanding. Please comment your concern to us, we may help you in your understanding on TCL Programmings. 1.        Write a program to print a string in TCL ? Ans –   Strings can be printed using double quotes, single quote or curly braces. Please refer the below example for trying dfferent variables. set a "TCL Programs" puts "$a" Output : tclsh main.tcl TCL Programs 2.        Write a program to accept two numbers from user and print their sum? Ans – puts "enter a number" set 1stnum [gets stdin] puts "enter another number" set 2ndnum [gets stdin] set result [expr $1stnum + $2ndnum] puts “Sum of both the numbers is $result” Output : tclsh main.tcl Enter a number 345 Enter another number 100 Sum of both the numbers is 445 3.  ...

-: Networking interview questions :-

1. Here's how the  Wireshark capture  would look during the first-time  ping  from Host A (10.1.1.1) to Host B (10.1.1.2). Since it's the first ping, there will be no pre-existing ARP entries, so you'll see both ARP and ICMP traffic. Packet Breakdown in Wireshark Each step corresponds to a captured packet with its main headers (Ethernet, ARP, IP, ICMP). Below is the packet-by-packet flow: 1. ARP Request Description : Host A (10.1.1.1) broadcasts: "Who has 10.1.1.254? Tell 10.1.1.1." Wireshark Protocol : ARP Packet Details : Ethernet Header : Destination MAC: FF:FF:FF:FF:FF (Broadcast) Source MAC: AA:AA:AA:AA:AA EtherType: 0x0806 (ARP) ARP Header : Operation: 1 (Request) Sender MAC: AA:AA:AA:AA:AA Sender IP: 10.1.1.1 Target MAC: 00:00:00:00:00:00 (unknown) Target IP: 10.1.1.254 2. ARP Reply Description : Router R1 (10.1.1.254) responds: "I am 10.1.1.254, my MAC is R1:1." Wireshark Protocol : ARP Packet Details : Ethernet Header : Destination MAC: AA:AA:AA...

100 Networking Questions

Basic Python Programming Write a Python program to reverse a string. (I have also added code for reverse a list) #Reverse a string a="Hello" try:     print(a[::-1])     #Reverse a list     b=[1,'a',"Suchi"]     print(b[::-1])     print(b[2])     c=b[2]     print(c[::-1]) except Exception as e:     print("Error Found"+e) Reasoning: [::-1]  is Python slicing syntax: :  refers to the entire sequence. -1  specifies the step (reverse direction). This avoids using loops, making the program concise and efficient. 2. Implement a function to check if a number is prime. num=23 if num<2:     print("Not Prime") for i in range(2,int(num**0.5)+1):     if num%i==0:         print("Not Prime") print(num," is Prime ") Reasoning: A prime number is only divisible by  1  and itself. Checking divisors up to the square root of  n  reduces time complexity...
