Question

How do I write not equal to sign (equivalent of != in C) in Latex pseudocode.

Do you mean $\neq$ ?

Or, what doesn't work for you using !=

If you want a literal != in a pseudocode listing, you can use \mathrel{\mathtt{!=}}. You could also use ≠ from the monospace font.

Unicode also has the symbol ⍯ from APL. It’s U+236F, and you can use it in LuaLaTeX or XeLaTeX.

$\neg$ is - and $\not=$ is the equal sign with the slash through the center
