C++ input  integer n , output n had how many digitals use loop example: input: 3124 output: 4 digitals input: 123 output: 3 digitals

E. The postfix form of the expression; A*B+C/D is: A АB/CD+ B A *BC+/D AB*CD/+ D ABCD+/*

• Write a program that asks the user to enter the size of a triangle (an integer from 1 to 10) • Display the triangle by writing lines of asterisks • The first line will have one asterisk, the next two, and so on, with each line having one more asterisk than the last line up to the number entered by the user. • On the following line, write one fewer asterisk and continue decreasing the number of asterisks by 1 for each successive line until only one asterisk is displayed. (Hint: Use nested for loops; the outside loop controls the number of lines to write, and the inside loop controls the number of asterisks to display on a line.) • For example, if the user enters 3, the output would be: Input Data: • An integer between 1 to 10 Set up an input validation loop to ensure the entered data is within range • As long as the entered data is not within range, the user is to be prompted repeatedly until the entered data is within range; at that point, then the valid input data is to be used to…
