c - How does one represent the empty char?

Question

I'm currently writing a little program but I keep getting this error when compiling

error: empty character constant

I realize it's because I'm trying to replace a valid char with empty space c[i]='' but I have not been able to find another way to represent it.

Answer 1

You can use c[i]= '' or simply c[i] = (char) 0.

The null/empty char is simply a value of zero, but can also be represented as a character with an escaped zero.
