Q$52$: What will be the output after the following C$++$ statements have been executed?

int a$\{4\}$;

int b$\{12\}$;

int c$\{37\}$;

int d$\{51\}$;

if $($a $<$ b$)\{$

cout $<<"$a $<$ b$"<<$ endl;

$\}$

if $($a $>$ b$)\{$

cout $<<"$a $>$ b$"<<$ endl;

$\}$

if $($d $<=$ c$)\{$

cout $<<"$d $<=$ c$"<<$ endl;

$\}$

if $($c $!=$ d$)\{$

cout $<<"$c $!=$ d$"<<$ endl;

$\}$

a$.$ a $<$ b

c $!=$ d

b$.$ a $<$ b

d $<=$ c

c $!=$ d

c$.$ a $>$ b

c $!=$ d

d$.$ a $<$ b

c $<$ d

a $!=$ b
