This program will calculate the sum of integer values.

Write a program that asks the user for a positive integer value (between 1 and 1000) and that uses a loop to validate the input. The program should then use a second loop to compute the sum of all the integers from 1 to the number entered. For example, if the user enters 50, the loop will find the sum of 1, 2, 3, 4, ...,50. */

#include using namespace std;

int main() { // TODO STEP 1: Declare 3 integer type variables: // - type int, named sumTo, to hold the user's entry of what to sum up to // - type int, named count, to serve as the loop control variable when summing // - type int, named total, to accumulate the sum // // Initialize the total accumulator to 0.

// TODO STEP 2: Prompt the user and get the number to sum up to (the sumTo) // (in the fashion demonstrated in the SAMPLE OUTPUT below).

// TODO STEP 3: Write a loop to validate that the user entered a number between 1 to 1000 // Display an error message if the user made an incorrect entry and prompt them to make // a new entry. Be sure to use the type of loop BEST suited for this circumstance, where // the user may make zero or more mistakes (though the exact number is not known) before // finally entering a value that falls in the correct range. Once again, refer to the // SAMPLE OUTPUT below to determine the correct formatting of the error message.

// TODO STEP 4: Write a loop to sum from 1 to the number the user entered (sumTo). // You will need to use the variable named 'total' to accumulate the sum and the variable // named 'count' will be used as the loop control variable. Be sure to use the type of // loop BEST suited for this circumstance, where the number of times the loop needs to // execute IS known before the loop starts. The number of times the loop iterates may // not be known before the program is run, but it IS known before the loop executes (and // the value should be stored in a variable if you did the steps above correctly).

// TODO STEP 5: Display the results to the user (in the fashion demonstrated in the // SAMPLE OUTPUT below).

return 0; }
