Hello

we normally develop softwares on perl , we need a code structure like that for C++

	    $udp_dst_ip{$dst_ip}{src}++;
	    $udp_src_ip{$dst_ip}{$src_ip }{src}++;
	    $udp_src_port{$dst_ip}{$src_port }{src}++;
	    $udp_dst_port{$dst_ip}{$dest_port }{src}++;
	    $udp_tos{$dst_ip}{ $tos }{src}++;
	    $udp_ttl{$dst_ip}{ ($ttl) }{src}++;
	    $udp_packet_length{$dst_ip}{ $packet_length}{src}++;
	    $udp_data{$dst_ip}{$full_data }{src}++;

udp_dst_ip is an hash table when ever i add sth in it , it add one to souce count
for ex.

udp_dst_ip : 185.9.159.2
udp_dst_ip : 185.9.159.3
udp_dst_ip : 185.9.159.4
udp_dst_ip : 185.9.159.2


that returns -> $udp_dst_ip{185.9.159.2}{src} -> 2

and this are double layered hash tables :   $udp_src_ip{$dst_ip}{$ttl }{src}++;  

for ex.

udp_dst_ip : 185.9.159.2  & ttl : 115
udp_dst_ip : 185.9.159.2  & ttl : 116
udp_dst_ip : 185.9.159.2  & ttl : 117
udp_dst_ip : 185.9.159.2  & ttl : 115
udp_dst_ip : 185.9.159.2  & ttl : 115

and this time  $udp_src_ip{185.9.159.2 }{115}{src} returns 3


is there any mechanism on C++ like that ?
