Assignment 2
1. Write a program to ask for a string from the user and then output the string in a
reverse order. If the output string is exactly the same as the original one then you
should also append “, and amazingly they are the same!” Here are a couple
examples (the part in italic is the user’s input):
Please enter a string: James
The new string is: semaJ
Please enter a string: sandnas
The new string is: sandnas, and amazingly they are the same!
2. Write a program to ask for an integer from the user – please note this “integer” is
only mentioned in the prompt so that the user won’t input a number of other types,
while you, as the programmer, can still treat this input as a string – and then create
a new number by switching the first half and the second half of the original integer.
Here are a couple examples (the part in italic is the user’s input):
Please enter a string: 123456
The new string is: 456123
Please enter a string: 56789
The new string is: 89756
3. Write a program to ask the user to enter a sequence of numbers (double type). The
numbers are separated by the return key (and give a prompt for each enter). The
user ends the sequence by entering a 0. Then output the maximum number of all
the entered numbers. Here is an example (the part in italic is the user’s input):
Please enter a sequence of numbers, separated by return, and then end this
sequence with a 0 at last: 25
Next number: 35.6
Next number: 112.112
Next number: 0
The maximum among your enters is 112.112
For all above programs you must also first output your name and your student number.
