Can anyone explain what is the benefit of comparing constant and variable with constant on the left e.g. 

if (0 == variable)

Instead of

if (variable == 0)

    To avoid accidental assignment, `if (variable = 0)`. If the constant is on the left-hand side, then it would be a syntax error: `if (0 = variable)` – Alex Shesterov Apr 15 '16 at 21:07

If you say

if (variable == 0)

you are under the risk of omiting one = and saying

if (variable = 0)

which will set the variable variable to 0.

So putting 0 to the left makes it more typo-safe, because 0 = variable won't be able to set any value to the variable.
