Task 3

Write a program to display the squares of all the numbers 1 to 100 in a

table format similar to the output displayed.

You have to make use of a loop.

create a program, name it PRGYOURNAMEFA1, that implements a search and replace function recursively. Your program should allow a user to enter a string , a substring to be replaced in the entered string and a character/s to replace the found substring 

Program Structure

1. A main class that implements the logic of the program – name this class TestSearchReplace

2. Add a class named SearchReplace to the main class with two methods, including:

a. SearchSubstring()- return method

b. ReplaceSubString() - void method

The two method should be called using an object in the main class. DONT CREATE THE TWO METHODS IN THE MAIN CLASS

Sample Output:

1 Please enter a string: Hello world

2 Please enter the substring you wish to find: llo

3 Please enter a string to replace the given substring:@@

4 Your new string is: h@@ world

Write a program that requests the user for 20 numbers and calculates the average of the numbers which are smaller than 10. You have to make use of a loop.

Write a program to display the squares of all the numbers 1 to 100 in a table format similar to the output displayed. You have to make use of a loop. (Note: the output shown here is only an extract of the output your program should give)

Write a program to display the numbers 8 down to 0 underneath one another, making use of a loop
