Print xth column of yth line

I have a file having fields in a matrix fashion.
What are the different ways in which I can print 3rd column of 5th row
(i.e. NF =3 and line = 5)??

Thanks

Like:

awk 'NR == 5 {print $3}' file

Try out how far you get with

awk 'NR==5{print $3}' file

let's play "flog" for a change ;-)
---------
awk -v col=3 -v row=5 '
FNR>row{
print a
exit
}
FNR!=row{ next}
{
for(i=NF;i;--i){
if(i>col){continue}
if(i<col){break}
a=$(i)
}
}
' yerfile
---------

Well yes indeed but it may show you may have missed the
"let's play 'flog' for a change ;-)" part?

as the OP wanted an undefinite number of solutions
here's another 'flog' way ,-)
---------
awk -v col=3 -v row=5 '
!(FNR-row){
split($0,v)
a=v[col]
print a
exit
}
FNR-row{
next
}
---------

that may be (due to lack in knowledge about english proverbs)

yup, and that'd make me a frog, maybe the reason why
flog's a natural ;-)
Or maybe Lorenz was thinking to that amelican plovelb?
"Can't tell by looking at a flog how high he will jump."

as you requested boggle here's a last and boggling flog,
I promise I won't push any other after that one ;-)
-----------
awk -v col=3 -v row=5 '
{
row--
while(++i){
a[++n]=$(i)
if($(i)~/[\n]/){
row--
}
if(!row){
while(++i){
a[++n]=$(i)
if($(i)~/[ \t]/){
col--
if(!col){
for(p=n-1;p;p--){
printf("%s", a[n-p])
}
printf("%s","\n")
exit
}
n=0
delete(a)
}
}
}
}
}
' RS= FS= yerfile
