Have you ever worked with bits/stdc++.h? Could you explain to me this program? And why can't it be compiled?

#include<bits/stdc++.h> using namespace std; struct node { string sourceIP; string destinationIP; string data; struct node *next; }; void searchPacket(struct node x) { if(x.sourceIP[0]=='0' && x.sourceIP[1]=='0' && x.sourceIP[2]=='0') cout<<"Source IP is suspicious."; if(x.destinationIP[0]=='0' && x.destinationIP[1]=='0' && x.destinationIP[2]=='0') cout<<"Destination IP is suspicious."; } bool cyphertext(struct node x) { for(int i=0;i<8;i++) x.data[i] -= 1; if(strncmp(x.data,"JOHN JAY",8)) cout<<"The data contains JOHN JAY"; } int main() { node abc[2][3]; for(int i=0;i<2;i++) for(int j=0;j<3<j++) { cin>>abc[i][j].sourceIP; cin>>abc[i][j].destinationIP; cin>>abc[i][j].data; if(j==2) abc[i][j].next = NULL; else abc[i][j].next = abc[i][j+1]; } return 0; }

I never use #include<bits/stdc++.h> I didn't even know that existed but I have used #include <bitset>

That header during compilation time will fetch all necessary header files required for the program .You don't have to include all necessary header files in your program.Instead bits/stdc++ does that work.

When i run the program, there is an issue with a header.

It depends on the type of compiler you are using .It works in Dev c++ but does not in the default compiler for Linux.Compiler dependent to be precise.
