My program allows a server and a client to chat over a socket. Currently I have to wait for one of them to type a message and press enter, before a message from the other person can be received.

Thanks! Got it working

Yes, the '-w' is essential. What command would you recommend to extract the number from the string?

I'm trying to get the number out of the argv[1] string.


argv[1] = -w50

line of code I'm using:


sscanf(argv[1], "%d", &columnWidth);

Jim can you show me an example of what such a line would look like? Scanning for 4 words in the string?

I input a line from a file, into a string called line. I then want to scan it to get all the individual parts of it, but I'm unsure of how to do that in c++.

Here's my code:


getline (myfile,...

Ah yes, fixed that.

I'm not familiar with the std::getline way. What would the code look like for that?

thank you.

This is what I'm using now: is this the best way to do it? ( it seems to be working fine)


int main()
{
char marks[15];

I'm trying to get string input from the keyboard for my assignment. For my assignment the user can input 1 of 3 things (there's no menu system to determine which - i have to be able to tell what they...

Thanks a ton!

I'm trying to write a program that wraps words to the next line if there isn't room for them in the current column. I have a function I've written but it doesn't work (apparently strcmp() only works...

Hi, I'm having trouble with an assignment I'm doing. My code is split across 3 files. My header, main, and functions, so I'll post all three.

Header: cA6_proto.h

#define MaxLineSize 100...

thanks a ton. I was messing around with sscanf() but didn't really wrap my head around it.

My string input can either be "-c123" or "-c 123".

What's the best way to scan the string to get the number out?

Hi, I'm trying to write a program that takes a text file as an output, and prints the text of that file to a column size defined by the user.

Here's my printing loop so far, when I run it, it just...

that cleared everything up, thanks a lot!

Oh ok, sorry, I'm only first semester of first year. My mistake:

here is my current code (all other files (header, functions) haven't changed:


#include"cA5_Proto.h"

int main(int argc,...

Thank you again for the help! upon further investigation it appears that my error is at the malloc() line:

Should my fileData after i allocate memory, be equal to fileLength?

I put in a print...

I made my program better, here's the new code:

cA5_Proto.h:

#include <stdio.h>
#include <malloc.h>
#include <stdlib.h>
#include <Windows.h>

thanks a ton, that helps a lot.

I do have a bunch of libraries included, I just didn't paste them into the code window, the libraries I have are (which are in my header file, my main includes the...

Hi, this is my first post, I'm having a lot of trouble with a C assignment that i have.

I have to get input from a binary file, get the size of that file using a function getSmallFileLength, then...
