Burning questions of the day

char: "tchar", "care"?
sprintf: "ess print eff", "sprint eff", "sprintfff"?
boolean: "boo lee an", "boo leen", "boo lay an"?
fmt: "format", "eff emm tee", "fumpt"?
racket: "rack-it", "rack-ay"?
daemon: "dee-mun", "day-mun", "diemin"?
cache: "catch", "kash", "kaysh", "kashay"?
enum: "ee numb", "ee noom", "eh num"?
var: "varr", "vair"?

I use the following:

char: "care"
sprintf: "ess print eff"
boolean: "boo lee an"
fmt: "format"
racket: "rack-it"
daemon: "day-mun"
cache: "kash"
enum: "ee noom"
var: "varr"
