How many times will this while loop code run

How many times does the following code run?

total = 0;

while (total < 100)

total = total + 5;

disp(total)

end;

I thought it was 20, but I am wrong?

[Jan]

To be exact, the code runs one time only.

It depends on whether you are counting the number of times the "while" statement executes or the number of times it will print a number. It will print 20 numbers, 5:5:100 . But the total<100 will execute one extra time to determine that the loop has ended.
