If the user enters a negative integer, the program should display an error message. The user ends the program by entering the sentinel of -1. In this program, the user has an indefinite number of integers and each iteration prints a number of stars thats equal to the read integer. Whats the suitable loop structure for this program?Below is a sample output. Include this output as one of your test cases.

Enter an integer: 4 Output:** Enter an integer 10 Output:**** Enter an integer: -3 Invalid input! Enter an integer: 8 Output:*** Enter an integer -1
