Question

USE of C++ please

Write a program that achieves the following requirements: 1. A while/do-While loop that will ask the user to input an integer on each iteration. The loop keeps a running total of the input and exits only when the total exceeds the first input times 10. 2. A for loop that does the exact same thing. The program should print out the *new* total each time the total is input.

Answer 1

#include<iostream>

using namespace std;

int main() {

int total = 0;

int first_input;

int input;

bool test = false;

//using do ... while loop

cout << "using do ...while loop :\n";

do

{

cout << "Please enter an integer :";

cin >> input;

if (!test) {

first_input = input;

test = true;

}

total += input;

cout << "New total is : " << total << endl;

} while (total < first_input*10);

//using for loop

total = 0;

cout << "\n\n\nusing for loop :\n";

for (int i = 1; i > 0; ++i) { //NOTE : this is an infinite loop

cout << "Please enter an integer :";

cin >> input;

if (!test) {

first_input = input;

test = true;

}

total += input;

cout << "New total is : " << total << endl;

if (total > first_input * 10) {

break;

}

}

return 0;

}

//Sample output
