Please, help me write the code in c++ following the pseudocode that is already written on the pic.

thank you!!!!

* Write a program that asks the user for a positive * integer value 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 up to the number entered. * For example, if the user enters 20 the loop will find * the sum of 1+2+3+3+...+20. // include libraries #include 11 add std namespace using namespace std; // start main int main() 17 declare variable to hold positive number entered by user int positiveInteger; // setup counter int startingNumber = 1; Il declare and initialize a variable to hold the sum int i = ; 11 prompt the user to enter a positive number cout
