Write a program that will repeatedly ask the user to enter a floating-point number. the program should continue to ask the user to enter numbers until a zero or negative number is entered. At that point, the program should display the largest number entered. Example: the largest number entered was: 47.5 Write a program that will ask the user to enter an integer. the program should add all the integers from 1 to the entered number using a "while" loop, and display the sum. Show how the "while" loop in problem 3 can be re-written using a "for" loop instead. Write a program that includes a function called sqroot() that returns the squareroot of a positive integer. in the function, use a loop to find the squareroot . If the number does not have an integer squareroot , the function should return a value of zero. in the main() function, ask the user to enter a positive integer, then call the function and display the result. If a zero is returned, it should display "No integer squareroot
