also a function to show usage

and a function to parse the arguments

the hardest part will be making sure my input is formatted how i want etc

wait, ill find easier code for that

//Demonstration of variables #include <iostream> #include <string> using namespace std; static void showUsage(char** argv) { cerr << "GNU area version 0.01-beta\n" << "Usage: area <width> <height>\n" << "Computes the area from width and height\n" << "\nUse -h to show help\n"; } int main( int argc, char** argv) { if ( argc < 3 ) { showUsage(argv); return 1; } unsigned short int Width = stoi(argv[1]); unsigned short int Length = stoi(argv[2]); // create an unsigned short and initialize with result // of multiplying Width by Length unsigned int Area = (Width * Length); cout << "Area: " << Area << endl; return 0; }

this is my first

okey the code i had is the examples from here but with spanish comments 😆

just try to understand the examples from gnu

they are quite basic

thanx

i undersand a little spanish

also after the examples you can see examples of outputs depeding on the input from commandline

here you have a folder with the examples

wow thank you very much

you are welcome :)

ohh you are in this group as well1

how would you check for loss of data due to type casting? in c++

when? compile time or run time?

compile time

probably a compiler warning option

how would i check for data loss ?

The best thing I can't think of is to define own cast

I didn't find info about that video.

WTF

Hey , im trying to overload the » istream operator

to read a word , not a string , how could i do that?

inherit from istream, then overwrite that method

would it work for you?

what you mean with a word and not a string?

oops, but istream operator >> default delimiter is blank, so you are already reading word-by-word basis, isn't?

Didnt knew that , thanks ^^

good luck getting a response from the admin :D

so, you are 1337 kali haxxors

but can you type ls -l

Nelson Mandela: How does one interchange the keyboard function of a pc

but can you type ls -l

>tfw aliased ls to ls -l

not ll la etc?

that's the usual convention

I hate how everything scrolls when you use ls -l

plus it's way to much info

good luck getting a response from the admin :D

I accept's

It doesn't matter if you announce another hacking group

But needs to be hacking or programming group, not cooking or fucking group

ls -hal

ls -hal

I'm sorry dave, I can't let you do that

😔

could you please send more spam please? 😆

delete your spam

Does it have anything to do with c or c++?

Don't abuse of this

maybe you could try to write in a way we can read

also maybe you yould try not sending 20 messages related to your wannabe kali group into a C++ group every hour

Go out with the problem

Yes, be afraid, he uses the ultim8 haxx00r distro called teh kali loonix!!!

in c++ whats the most direct way of testing for parts of a string?

lik in python i can use myarray[1:5] for example

to test for myarray[1]-myarray[5]

String comparison, character searching...?

Strcmp from cstring if you use char*

if you know for sure that your string is at least 1 char long, you could use strncmp(your_str, other_str, 4) for comparison, strnchr(your_string, your_char_searched), strnpbrk...

i used myString.substr()

oops, I read plain C, don't know why 😅 Then is better to stick with std::string interface :)

they are less error-prone

is C++ supposed to be big files, im very new to c++ but my program does very little and is 14K

im used to x86asm

all it does is handle two flags and print out a few lines it just seem like a huge file

not really... it depends on what you tell your compiler and what constructs you use

I never cared about size but I heard templates use a lot of space
