How do I write the following if statement in C? 1

[Rmcta]

I need to say:

if x number is between a and b
and y number is between c and d
Then . . .

I tried the following but does not work:
if( (4>=12) && (4<=20) && (16>=15) && (5 <=11) )
do this
else
do that

Seems good to me - with appropriate substitutions for x,y,a,b,c,d
