(SOLVED) for_while!! x, sum integers are not defined in this scope, why?

Question

#include <iostream>
using namespace std;

int main()
{
do
{
int x = 0;
int numbers = 0;
int sum = 0;
x++;
cin >> numbers;
sum = sum + numbers;

}while(x<=5);

cout << sum;
return 0;
}

Answer 1

fergoka you have defined sum inside do which will be treat as local variable.

Do like this:

int sum = 0;

do {
sum += 5;
} while (x <= 5);

Answer 2

You haven't defined x and sum in the in the main function ,they are only defined in the do Loop scope

intialize and define outside do Loop
int x=0;
int numbers;
int sum=0;

Answer 3

Uf..how silly I am. Thank you, AJ!
