I was windering, if you are writing a C program, I don't think you are supposed to commit the .o files and executables. How can you test your program without making a copy outside the git working dir?

Few months back I learnt a *few* concepts about bits/bytes and started writing a program for bit packing in C++. Now that program has grown upto 600 lines and I am still working on it. Yesterday I realized I missed some special cases due to which the program was malfunctioning. Now I have modified the program and it is working properly but I think If I would have designed all the possible test cases before writing the code, I would have finished the program long ago.
I. What is proper way to design the test cases before coding?
II. How should I make sure that I do not miss any cases while making the test case doc. ?
III. Does writing test cases prior to coding solve messy code issues or should I consider something else ?
I wrote a test program to get the CPU utilisation. I hope to extend it to take cpu utilisation on multi core machines. Hear I used the equation for taking cpu utilisation given at [url] of JmSchanck post. But when I match the output of my program against 'top' and 'system monitor' output it seems quite high. Sometimes cpu utilisation goes more than 100%.
So the given equation in that url is correct? can anyone give me the equation to take CPU utilisation?

Basically, it is a Bluetooth scanner that is designed to do just one thing, scan for discoverable devices in range and record their MAC, name, and the time/date they were found to a log file. There are only a few options, it is pretty much a set it and forget it sort of thing. The only requirements are BlueZ (3.x or 4.x), and that your computer has a Bluetooth device that is supported by Linux.
Obviously you will also need at least one device to scan for, and the more the better. If you want to take a walk through your mall while running it and seeing what you found, I would be ecstatic. A word of warning, I am not a very good C programmer and I have no doubt that there are mistakes in the code and improvements that could be made. You can download the source and get a little more specific information about it from: [URL].
I started to run a C++ my program in Linux and I don't know how to test my program that works fine with a text file. This is a project for my uni and to explain more clear, My program is a sample database for modify or add and search and it read data from a binary file and also write into a binary file. I have got an input from my lecture and she said after compiling in Linux I must write:
1-to compile:
Code:
g++ (files with cpp)
2-to see the output:
Code:
./a.out
3-to test with input:
Code:
./a.out < input.txt >
My problem is in step three. What I must write in the command part after" step2" to see the output?

View 1 Replies View RelatedI want to simulate a serial protocol in user space program to test reception algorithm. The protocol is similar to UART protocol but frame format is different. The duration of 1 bit is 114,46 us. In my main function I'm creating two threads. Tx for simulating transmitting data and Rx for reception data. For measure time I use create_timer() function and signals. Each thread has its own timer and signal handler. Tx timer uses SIGUSR1 and Rx timer uses SIGUSR2. Tx thread sets the global variable and Rx reads it.
The timers are set to sample with 114,46 us period. When they reach this value signal handler should set the flag. Flag is check in thread and some operation are made. When I set the timers period for longer time (100 ms) everything works fine but when I change it to default value (114,46 us) the Rx thread doesn't receive the proper data. I am wondering if the 114,46 timer period is possible to simulate in user space? Whether the time will give me the proper resolution ? Theoretically it should provide 1 ns resolution.

For example, say my "code" is actually config files for Apache, and I wan't apache running on machine B to update it's config files based on the files found in tag "release-1.0", how is this done?
I'm sure the solution is very easy, but I just can wrap my head around it.
Is there anything like burning rom from nero or roxio cd/dvd copier. Do you know of any dvd copying program? like without making the image and then burning with just one process just copy the disc sorta program like roxio dvd copier? I wanted to make copies of movies I made a dvd of but aside from image burn which is a hassle to make the image first. is there something for burning on the fly or dvd/cd copying? infrarecorder and cdburnerxp do not work for me at all.

View 3 Replies View Relatedmake a simple script to copy files from my "hfiles " directory to a "www" folder at leats I think its a directory, it has the permissions as "lrwxrwxrwx " but its like a public branch So I proceeded to make a file entittled MkPublic to copy the "hfiles" directory to the "www" branch
here is the code i used:

when i try to run the script it tells me that there is a syntax error and an unexpected end of file and nothing seems to get copied anywhere so clearly there is something wrong with one im doing, i tried multiple ways : using the quotes, spacing the equal signs, but I seem to still get the same results.

Also 'Ubuntu Software Centre' & "Synaptic' thingy come up with errors, saying can't install or uninstall progs. Although it seems they may do it OK despite saying they can't. Have Computer Janitor installed, but this is no longer working at all. So... is there a program or such that I can use to test/clean out the system?? For that matter, is there a program for testing hardware, as I'm not sure if it's an indication of unhealthy hard drive or such?
