Assume that a variable temperature is assigned like this:
var temperature = 30;
Choose the two (2) Boolean expressions that evaluate to FALSE. - correct answer ✔✔(temperature == 0)
|| (temperature > 32)
, Consider the code segment below given in pseudo code (see reference above). Assuming that variables
a, b and c already have numeric values assigned to them, what is the expected output of this code
segment?
val <- a
IF(b >= a AND b >= c){
val <- b;
}
ELSE
{
IF (c >= a AND c >= b)
{
val <- c;
}
}
