Hello, I need help with while loop please help Use a while loop to add all of the even numbers up: 2 + 4 + 6 + 8 + · · · until the sum exceeds 5 million. What is the actual sum? How many even numbers were added?

An example how the while loop works
If we have to do 1+2+3+4+...+10
s=0;
k=0;
while k<10
k=k+1;
s=s+k
end
Try to adapt this to your problem

For homework questions it is recommended to show, what you have tried already. Then the forum can help to solve a specific problem.
Note that Gauss has found a formula to solve the addition in several seconds without a computer. You can re-order the terms of his formula to solve your problem also.
