initilize a variable to a blank character

[kalp1200]

hi..

how do I initialize a variable to a blank character;

I tried char z = " ";
but keep receiving this -- error C2440: '=' : cannot convert from 'const char [2]' to 'char'


I am writing a program on functions..

double quotes are used for strings.
single quotes are used for chars.

char z = ' ';
