Write a complete program that: 1. Uses a do...while loop to prompt the user to enter a count that is greater than 1 and less than or equal to 20 then reads in a count from the keyboard as an integer. a. If input error occurs or the count the user enters is less than or equal to 1 or greater than 20, output an error. After outputting an error, clear/ignore the failed input and continue do...while looping until a valid number is entered. 2. Writes a triangle to the display using for loops. The triangle will be upside down. To write this triangle to the display: a. amountOfStars = number entered in (1). b. Output amountOfStars followed by a new line. Decrement amountOfStars by one. C. d. Continue from (b) until amountOfStars is zero. 3. Writes a triangle to the display using while loops. The triangle will be rightside up. To write this triangle to the display: amountOfStars = 1. a. b. Output amountOfStars followed by a new line. C. Increment amountOfStars by one. d. Continue from (b) until amountOfStars is greater than the number entered in (1). Your program must handle the possibility that the user accidentally enters a character or out of bounds number. If a character or an out of bounds number is entered, the stream should be cleared, any previous values read should be discarded, an error displayed, and the user prompted again. The program should not exit until good values have been entered.

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.

Transcribed Image Text:Write a complete program that:
1. Uses a do...while loop to prompt the user to enter a count that is greater than 1 and less than or equal to 20 then reads
in a count from the keyboard as an integer.
a. If input error occurs or the count the user enters is less than or equal to 1 or greater than 20, output an error.
After outputting an error, clear/ignore the failed input and continue do...while looping until a valid number is
entered.
2. Writes a triangle to the display using for loops. The triangle will be upside down. To write this triangle to the display:
a. amountOfStars = number entered in (1).
b. Output amountOfStars followed by a new line.
C. Decrement amountOfStars by one.
d. Continue from (b) until amountOfStars is zero.
3. Writes a triangle to the display using while loops. The triangle will be rightside up. To write this triangle to the display:
amountOfStars = 1.
a.
b. Output amountOfStars followed by a new line.
C. Increment amountOfStars by one.
d. Continue from (b) until amountOfStars is greater than the number entered in (1).
Your program must handle the possibility that the user accidentally enters a character or out of bounds number. If a character or
an out of bounds number is entered, the stream should be cleared, any previous values read should be discarded, an error
displayed, and the user prompted again. The program should not exit until good values have been entered.
