Answer:
Binary information must be encoded in some way before transmission over the Internet. ... Copper wire is used to transmit binary messages using electricity - a voltage on the wire means one state, and no voltage means the other. Fiber-optic cables, on the other hand, use light (on or off) to transmit a binary message.
Incorrect data can lead to unexpected program execution results. Data entry errors can be reduced by only accepting valid input, e.g., if a number must be entered, alphabetic characters are ignored. After data validation, error messages can be prompted to the user, requiring him to enter the data again.
Answer:
#read value of name
name=input("Enter name:")
#find and ptint the last character of the string
print("last character of string is:",name[-1])
Explanation:
Read a string from user and assign it to variable "name".Find its last character as "name[-1]". Since name is character array,so name[-1] will give the last character of the array.
Output:
Enter name:Smith
last character of string is: h
Answer:
Handle the exception in a catch block or throw the exception to the method that called this method.
Explanation:
The try and catch statements occur in pairs. The try statement allows the user to define a block of code to be tested for errors while it is being executed.
The catch statement allows the user to define a block of code to be executed, if an error occurs in the try block.
If an exception is checked by a method, the method either handles the exception in a catch block or throw the exception to the method calling it.
