a)using notepad,prepare a text file with marks for 8 students on seperate lines. The program will then read this file and store all the marks into an array.
b)It will then calculate the average marks.
c)Finally, displays all the marks and average marks on the screen.
would you be kind enough to give me the workout solutions.
I have included fstream in my file (#include <fstream>) In the file, I have a class declaration and a private variable static fstream fileStopWatch; Then I am getting the error "'fstream' does not name a type" It was working in gcc version 4.1.2 20080704 (Red Hat 4.1.2-48) but not working in gcc version 4.4.4 (GCC)
[Code].....
I'm trying to attach an fstream to serial port for reading and writing with the following code:
Code:
#include <iostream>
#include <fstream>
#include <string>
[code]....
The code compiles without errors, but doesn't catch any input text from the device attached to RS232. I have tried it with Rx and Tx connected, but didn't receive my text back. It works OK if I substitute /dev/ttyS0 with an ordinary file, but any attempt to use /dev/ttyS0 seems to lead to an empty answer string. I tried this on a PC under Ubuntu Linux 7.10.
Will a program (created using Real Studio) that's placed in the startup queue run? I tried just this, and while there was no error at startup it appears the program had no effect. It is a shell execution to set my screen-blanking time. The program does work once I am up and running though. I am using Linux Mint 8 on a T30 Thinkpad.

View 1 Replies View RelatedI have some novice to intermediate programming skills from a past life. What I want to do is create a program and run it on two separate computers to just get them communicating together over the network on a basic level. I would like to do this in a language that doesn't limit me to a specific OS, this way I can have a linux and windows computer talking. However, I would prefer a language that can be useful down the road as well. My second inspiration, next to networking, is web design and web programming, which I hope to dig into as well eventually.
I'm not aiming to do anything overtly-complicated. One example that comes to mind would be a program that forwards any typed characters on one computer over the network and displays them on the other, and vice-versa. I guess the program would run over TCP/IP. However, it would be nice to learn how to do this in a language that not only works on multiple OSes, but also has the ability to allow me to program my own communication protocol, aside from TCP/IP, down the road. My intention with all this is to learn some network programming for fun.
I need a program that automaticly runs this command in the terminal when I use it:
sudo modprobe nvidia_g210m_acpi
Sure, I know that it's not that hard to just write it in terminal and so on, but I really want a program for it. I'm using ubuntu 11.04 if U need to know that?

I have 2 questions... I couldn't find answers by Googling (more precisely, by Blackling) and in GCC documents, so I'm asking here.
1. There are 2 flags for position independent code, -fpic and -fPIC. All the examples I read use -fPIC... so when is -fpic useful and what is the difference?
2. Some tutorials use "g++ -shared" while others use "ld" for the creation of the shared library. Why? Does it matter which method I use? Is there a difference? Why does nobody mention both options?
I need to create a program where the user creates an account and he/she is entitled to add interests and creating friendships with other users.The main algorithm depends on an object which is the user and its attributes are adding interests, friends, so on.Users are stored in a linked list while their interests are stored in another list.What I want to do is every time a new user is created dynamically create a new list during execution for personal info. storage. Is that possible?

i dont see any error (you might)but every time i run it it runs but after it asks me to input for the width i do it but it doesn't take me to the length, it just stays blank until i input another value in the same place for the width, it asks me for 4 inputs in total i don;t know why, and after i run it different times it gives me different values for the perimeter and are. how can I fix this?

1. display menu until user quits the script
2. menu would give following options to
a. create backup
b. restore files from backup
c. quit
3. for option a or b user would be required to specify the files and name of the archive]
4. has option to be run with use of parameters if that is the case it will not display menu but carry out required task unless it was not possible to do
5. incase of any errors are encountered it would call external scrpit that would display custom disigned error message.

I wrote a script for capturing port 5060 with tshark.Well, it's only a line, but I needed to send a positional var, and I couldn't do it with an alias. Now I need that script to run as a service, so I can start/stop. (Using CentOS)
Code:

One more thing, my goal is to start/stop the service with

Is that possible? I read that I must use chkconfig.
