Question

c++ Write a for loop that computes the following sum: 5+10+15+20+...+485+490+495+500. The sum should be placed in a variable sum that has already been declared and initialized to 0. In addition, there is another variable, num that has also been declared. You must not use any other variables.

Answer 1

Answer:

#include <iostream>

#include <cstdlib>

 

using namespace std;

 

int main(){

 

 

   int sum=0, num=5;   //variables declaration and inicialization

 

   while (sum<500){   //conditioning to do the sum up to 500

   sum=sum+num;     //actually sum process

   cout << "The value is: "<<sum;   //show the result in screen

   };

   return 0;

}
