Can anyone replace FOR loop with WHILE loop?

for k=1:10
    x=50-k^2;
    if x<0
      break
    end
  y=sqrt(x)
end

Answer 1

[Andrei Bobrov]

k = 0;
x = 0;
while x >= 0
    k = k + 1;
    x = 50 - k^2;
end
y = sqrt(x);

x =

   -14 ? why?

x have to plus (+)

Not in your code. Your "for" loop tests x<0 after it sets x to the new value. So the loop is not going to end until it is already true that x<0.
