Why

so you can ban yourself :)

MᏫᎻᎯᎷᎷᎬᎠ

Is there way to use system function directly code : #include <stdio.h> #include <stdlib.h> int main() { int i ,a ; puts("Enter Your Number : "); scanf("%d",&a); FILE *f ; f=fopen("iptables.sh","w"); for(i=2;i<=256;i++) { if(i!=a) { fprintf(f,"iptables -A INPUT -s 192.168.1.%d -j DROP\n",i) ; fprintf(f,"iptables -A OUTPUT -s 192.168.1.%d -j DROP\n",i) ; } } fclose(f); return 0; }

sorry I don't read C

Trivially copyable types are "location-invariant" and users can specialize this trait for other types.

btw what does this quote means?

MᏫᎻᎯᎷᎷᎬᎠ

stop

what does Location-invariant means?

I saw that

🐰🐾 سمیه

here, you are doing ((((2 * 10) + 4) * 10) + 6)

Right, I got it now. Thanks

what does Location-invariant means?

And thank you 👍🌷

Are you cs student?

Is there way to use system function directly code : #include <stdio.h> #include <stdlib.h> int main() { int i ,a ; puts("Enter Your Number : "); scanf("%d",&a); FILE *f ; f=fopen("iptables.sh","w"); for(i=2;i<=256;i++) { if(i!=a) { fprintf(f,"iptables -A INPUT -s 192.168.1.%d -j DROP\n",i) ; fprintf(f,"iptables -A OUTPUT -s 192.168.1.%d -j DROP\n",i) ; } } fclose(f); return 0; }

Use the fopen and write/read sysremcalls

BinaryByter

The location doesnt change in ram

BinaryByter

Probably referring to the member functions

virtual function

I mean change fprintf by system dirrect without making *.sh file for(i=2;i<=256;i++) { if(i!=a) { fprintf(f,"iptables -A INPUT -s 192.168.1.%d -j DROP\n",i) ; fprintf(f,"iptables -A OUTPUT -s 192.168.1.%d -j DROP\n",i) ; } }

I mean for(i=2;i<=256;i++) { if(i!=a) { system("iptables -A INPUT -s 192.168.1.%d -j DROP\n",i) ; system,"iptables -A OUTPUT -s 192.168.1.%d -j DROP\n",i) ; }

it is syntax error

Anonymous

is there way to make value of i instead of %d in for statment ?

Avezy

You mean Like sprintf?

Anonymous

#include <string> int main() { std::string s; std::cin >> s; std::cout << s << std::endl; return 0; }

Now how to clear the screen? system("cls"); isn't working aand clrscr(); isn't working too

Furkan

Spawning new process is a heavy operation

Furkan

Instead use os api

Furkan

You can list api calls of cls via "dumpbin /imports cls.exe

Furkan

Dumpbin comes with windows sdk

#include <iostream> #include <vector> #include <string> using namespace std; class Test{ private: string name; vector <int> attribut ; public: Test(){ } Test(string name){ name = name; } string getName(){ return name; cout << "getname say Hello world" << endl; } void setNom(string name){ name = name; } }; Hi, freinds. If I run this code I dont get the name of object but if I use this in contructor I get it

Isaac

I thought that this is not required in this case but, .. Can someone explain it me

Isaac

int main() { Test t("caasi8"); // t.name = "caasi8"; cout << "main say hello world" << endl; cout << t.getName() << endl; return 0; }

Isaac

this is the main 👆

MᏫᎻᎯᎷᎷᎬᎠ

In setName

MᏫᎻᎯᎷᎷᎬᎠ

You forgot to use "this"

MᏫᎻᎯᎷᎷᎬᎠ

this->name = name

Note: Don't write anything after return statement (unless it's in a conditional block) Cuz anything below return statement won't be reached

god doesnt exist

Actually defination of god is so generic that it doesn't make enough sense to understand what people mean by it.

Pm me and I'll tell you

Trevor

WTF

Isaac

You forgot to use "this"

Ok, thanks, do you mean that in a setters methods I have to use this ?

MᏫᎻᎯᎷᎷᎬᎠ

Yeah You don't have to But in your case you have to

MᏫᎻᎯᎷᎷᎬᎠ

The parameter is name And the member variable is name

MᏫᎻᎯᎷᎷᎬᎠ

The parameter variable hides the member variable

MᏫᎻᎯᎷᎷᎬᎠ

If it was the same name

Isaac

ok, thank you very much

MᏫᎻᎯᎷᎷᎬᎠ

Your welcome

Dima

Lol

Dima

WTF

Indeed

Isaac

In fact, I think that the right explanation is that I must use this in the constructor that take name like param.

Manoj

I need a logic for truncating a string without using a loop like ex:COLLEGE is a string the output must be: C CO COL COLL COLLE COLLEG COLLEGE

Wherever you want to use That is the only way to distinguish between two identifiers that has the has the same name in class

Anyone plz

Now how to clear the screen? system("cls"); isn't working aand clrscr(); isn't working too

Did u include cstdlib Because I think system ("cls")is in it

Ok, good now thinks

Hello, i'm "new" in c++ programming, i'm studying it at school, and we only made basilar things, do some of you have some exercises to do? Because i wanna pratice and learn more about c++, thanks :D

BinaryByter

basilar

BinaryByter

Now how to clear the screen? system("cls"); isn't working aand clrscr(); isn't working too

dont clear the screen

BinaryByter

Use ncurses
