- Problem 1. Write a program that asks the user for a positive nonzero integer value. The program should use a loop to get the sum of all the integers from 1 up to the number entered. For example, if the user enters 50, the loop will find the sum of 1, 2, 3, 4, . . . 50.arrow_forwarduse C# programming Write a program that prints multiples of 7 in ascending order up to 100 on a single line. The program prompts the user for the start value. Don't be confused with increments and multiples. Type of loop-> whilearrow_forward2. Write a program that uses a while loop to play a number guessing game. The computer should pick a number using random number generation and then continue asking the user to guess the number until they get it right. For each, gues, the computer should tell the user if the guess is too high or too low or is correct. 3. Using nested for loops, right a program that displays a bar chart (using asterisks) for a number entered by the user. For example, if the user enters 4, the bar chart looks like this:arrow_forward
- Write a for loop that displays the following set of numbers: 0, 20, 40, 60, 80,…..1000 (Note there is a comma between the numbers but not the last one)explain please.arrow_forwardEXERCISE 19 Write a program using for loop that generates a multiplication table for any integer (given by the user) up to any multiple (also given by the user). Your output should be similar to what is given in the sample below. Sample Output >> exercise19 Enter the number for which you want to create the multiplication table: 91 Enter the number up to which multiplication table is required: 5 91 X 1- 91 91 X 2 = 182 91 X 3 - 273 91 X 4 - 364 91 X 5- 455 >> Electronic Engineering Technology---MATLAB Tutorialarrow_forwardIn C code, Write a for loop that prints all the even integers from 80 through 20 inclusive, separated by spaces.arrow_forward
- Program - Python Write a program asking the user to keep entering in strings (ie names) until they enter the string “leave”, at which point you’ll exit the loop and tell them how many times they entered the string “gold”. This one requires that you use a loop and also keep a tally of the number of times they enter the string gold.arrow_forwardWrite a FUNCTION that asks the user to input a string. Unless the user inputs "END" or "end", a loop will execute wherein the user is asked to input a string. Each time the loop runs and the user input a string, the function does the following: +Print the number of letters in the string that the user inputs; +Print the number of digits in the string that the user inputs. When the user enters "END" or "end" the loop stops and the function prints the aggregate numbers of letters and digits that the user has entered from the beginning. Example: 1st loop: a8K6H => 3 letters and 2 numbers 2nd loop: THGF*T425 => 5 letters and 3 numbers Aggragates: 8 letters and 5 numbersarrow_forwardWrite a number-entry loop. The loop should repeat 10 times and total the numbers entered.arrow_forward
- Code should be in Python. Prompt the user to enter a string of their choosing. Output the string.Ex: Enter a sentence or phrase: The only thing we have to fear is fear itself. You entered: The only thing we have to fear is fear itself. Complete the get_num_of_characters() function, which returns the number of characters in the user's string. We encourage you to use a for loop in this function. Extend the program by calling the get_num_of_characters() function and then output the returned result. Extend the program further by implementing the output_without_whitespace() function. output_without_whitespace() outputs the string's characters except for whitespace (spaces, tabs). Note: A tab is '\t'. Call the output_without_whitespace() function in main().Ex: Enter a sentence or phrase: The only thing we have to fear is fear itself. You entered: The only thing we have to fear is fear itself. Number of characters: 46 String with no whitespace: Theonlythingwehavetofearisfearitself.arrow_forwardprogram4_1.pyWrite a program that uses a for loop and the range function to examine all integers from 999 down to zero. Code in the loop should print multiples of 40 on one line separated by spaces, but with only six on each line. See Required Output. Use a counter to determine when six multiples have been printed. A counter is a variable that is initialized to zero and incremented by one when the event to be counted occurs. Include pseudocode.arrow_forwardThis program in C++ obtains a series of letter grades as input from a user. The program should calculate and output the total grade points and the grade point average (note: you may have to track the total number of inputs and the grade points to calculate the grade point average). The algorithm should execute 3 times for testing purposes.Use the appropriate loop for the main structure of the program that will stop accepting letter grades when the user inputs X. Also, choose the appropriate selection statement to convert the letter grade to the correct grade points.Additional Requirements:• Use appropriate data types and variable names throughout the code.• Use constants appropriately. Output needs to look like the image below.arrow_forward
