Types of Loop
Loops are the elements of programming in which a part of code is repeated a particular number of times. Loop executes the series of statements many times till the conditional statement becomes false.
Loops
Any task which is repeated more than one time is called a loop. Basically, loops can be divided into three types as while, do-while and for loop. There are so many programming languages like C, C++, JAVA, PYTHON, and many more where looping statements can be used for repetitive execution.
While Loop
Loop is a feature in the programming language. It helps us to execute a set of instructions regularly. The block of code executes until some conditions provided within that Loop are true.
The foreach loop is made to operate with the __________, which is a temporary, read-only variable.

- 1Write a for loop that repeats seven times, asking the user to enter a number. The loop should also calculate the sum of the numbers entered and display the final sum. 2Write a for loop that displays the following set of numbers: 0, 10, 20, 30, 40, 50 . . . 1000 What’s the initialization step? The Boolean test/condition? Update action/incrementation? 3Convert the while loop in the following code segment to a for loop: int count = 0; while (count < 50) { System.out.println("count is " + count); count++; } 4Convert the following for loop to a while loop: for (int x = 50; x > 0; x--) { System.out.println(x + " seconds to go."); } 5Write the complete Java program for problem #1 above. Name the class SumSeven. please solve 4 and 5Finish this program from the code posted below! Note: There should be two files Main.py and Contact.py You will implement the edit_contact function. In the function, do the following: Ask the user to enter the name of the contact they want to edit. If the contact exists, in a loop, give them the following choices Remove one of the phone numbers from that Contact. Add a phone number to that Contact. Change that Contact's email address. Change that Contact's name (if they do this, you will have to remove the key/value pair from the dictionary and re-add it, since the key is the contact’s name. Use the dictionary's pop method for this!) Stop editing the Contact Once the user is finished making changes to the Contact, the function should return.
