Here is my program. It asks the user for input and then prints a shape of a certain length. The errors I get when I compile are:
shape.c: In function "main":
shape.c:22: error: expected identifier or "(" before "int"
shape.c:58: error: expected expression before "return"
shape.c:59: error: expected expression before "}" token
shape.c:59: error: expected expression before "}" token
#include<stdio.h> .....
I've been working on it for over 20 hours and I'm stuck. It asks the user for input and then prints a shape of a certain length.

Code:
How would I best achieve this:
- Draw some shapes and gradients with QPainter/QPen etc
- Create a splash screen out of it
- Display SplashScreen.
I cannot find anything that doesn't involve

I am comfortable making splash screens out of images, but now I want to try drawing one myself.

First off, I'm completely new to bash scripting so forgive me if I make any egregious errors. I'm trying to make pop-up reminders for the simple calendar program when. This is what I have so far:
Code:
#!/bin/bash
# set the time format for when
#current="$(date +%I:%M %p)"
current="$(date +%-l%p)"
today=~/.when/today
[Code]....
When I run the script, gxmessage pops up and displays the correct information, but it does so for each line in "~/.when/today" that contains a time that matches the current system time (which would be three pop-ups at 10PM, according to the example). I want it to display the information only once. How can this be accomplished? Is a while loop even the right job for this?
After running for a while, often after starting a program that displays graphics, such as Shutter, Gimp, Ocular, or maybe simply having previews in Dolphin (as some of my folders default to large previews)most menus, and some windows will go completely black. Some simply grey out (only ksystemlog does this that I have noticed so far)Blindly clicking anywhere on top title bar has no effect (would expect minimize/maximize etc to work if hitAlt-leftmouse or alt-middlemouse will allow window move/resize - black actively conforms to new window size/shape.
Often this blackening is preceded by a loss of all global hotkeys, which may not be related.With no visible menus or buttons, and with no hotkeys I am forced to hit the PC power button and allow kubuntu to shutdown.If I am lucky and hotkeys still work i can simply log out with ctrl-alt-shitft-del and logging in again fixes the issue.Linux betlogbox 2.6.32-23-generic #37-Ubuntu SMP Fri Jun 11 08:03:28 UTC 2010 x86_64 GNU/Linux

I am supposed to create a script that displays the directories alphabetically with the size of each directory on the left hand size. I know you should use du to check for disk usage. So far i got the directories to display but not alphabetically.

I'm attempting to install a small application called Asymptopia Flashcard System on Xubuntu x64. It's unsupported and virtually unknown, so I don't know many details about it aside from what I can gather from the source files. The first step in the installation directions is to type "make lib_install" as root at the command line. I get this output:
Making libasymptopia.so ... compiling Path.C ... Path.C: In member function �void Path::listdir(char*, std::deque<char*, std::allocator<char*> >*): followed by a bunch of errors like this: Path.C:38: error: �strcmp� was not declared in this scope
all for the file Path.C, all of them complaining about various header files not being declared. I have the latest version of gcc installed, so I'm very confused about what the problem is. This application is at least a few years old...maybe there's something out-of-date about the way it includes the header files?

I have a Macbook Pro which i want to install Opensuse 11.2 64bit(Upgrades to 11.3) The problem is that once i install opensuse and then boot via rEFIt, it loads up till the desktop is supposed to appear. All i get at this stage is darkness with a few coloured shapes in the background (Video driver not loaded).I can however reboot and go in via the failsafe option. Once in here i can use the GUI. I am a total noob with linux, can some one give me the instructions on how to install this driver. Its driving me insane.

im trying to build a simple program for my C programming class, this is the source code
#include <stdio.h>

perimeter = width + length + height;
area = width * length + heigth;
[Code]...
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?

View 7 Replies View RelatedI've generated some srt subtitle files using gocr from pgm files used in DVD's. The ocr program gets confused between lower case L and upper case i and sees them as the same thing. This results in words with capital i's in them instead of lower case L.
What is the best way to automate the correction without a spell checker? I tried sed, but it's difficult to tell between the i's that you want and those that need changing. I figured that any word that consists solely of capital i's is ok, e.g. Roman Numerals, but any capital i not at the beginning of a word needs changing.

The 2010 CWE/SANS Top 25 Most Dangerous Programming Errors is a list of the most widespread and critical programming errors that can lead to serious software vulnerabilities. They are often easy to find, and easy to exploit. They are dangerous because they will frequently allow attackers to completely take over the software, steal data, or prevent the software from working at all.
The Top 25 list is a tool for education and awareness to help programmers to prevent the kinds of vulnerabilities that plague the software industry, by identifying and avoiding all-too-common mistakes that occur before software is even shipped. Software customers can use the same list to help them to ask for more secure software. Researchers in software security can use the Top 25 to focus on a narrow but important subset of all known security weaknesses. Finally, software managers and CIOs can use the Top 25 list as a measuring stick of progress in their efforts to secure their software.
