Use the function in case of a fatal error. This will undoubtedly abort the program.
TH1 is the basis of all histogram classes in ROOT.
A similar TMemFile is just a regular TFile, except that it only reads from and contributes memory.
Return 2 numbers after gaussian c and still mean=0 sigma=1. This
if it were, it could be; and if it were easy, it would be so; it’s not the same situation, it’s not the same. This is logic.

Mathematically proved a long time ago that it’s actually impossible to create sensitive enough software without bugs. As the number of variables increases, so does the complexity of subroutines and objects associated with interactions, and so does the underlying sound judgment about the program, the judgment that surpasses the ability of a single person to understand everything at once, errors clearly creep in tsya. in code. Since Root Tuts 7 is probably the most complex software ever developed, the bad news is that in the rarest of cases, there are undoubtedly problems.
This does not mean that you are guaranteed uninterrupted work with your computer. Far from there. Third-party programs also cause most computer problems, either because they themselves have problems or because they can’t work with Windows 7. Using software, devices, and devices designed for Windows 7 can be very rewarding, as can the maintenance program described in the chapter. 7, Maintenance of your Windows 7 system. But computer-related circumstances, such as the notorious death and money, are an integral part of life, so buyers need to know how to troubleshoot and fix problems that will inevitably come your way. In this chapter, I will help you do just that by sharing my popular troubleshooting methods and introducing you to all the Windows 7 recovery tools.
The origin of the word “mistake”
Software bugs are traditionally bugs, although many developers avoid the term because it has too many negative connotations these days. Microsoft, for example, loves the euphemistic “problems” term. There is an attractive and popular story about how this meaning of the word “termite” came about. To tie the story together, in 1947 one of the first computer brands, Grace Hopper, was working on a system called the Mark II. While investigating the problem, she found a moth between the hoses of the carpet cleaner, so that’s where the trouble is. called bugs. The story is certainly ingenious, but this scenario was not all the source of “computer bugs”, which means “bug”. In fact, engineers have been calling mechanical defects “mistakes” for at least 60 years before Ms. Hopper’s discovery. As evidence, the Oxford English Dictionary offers the following quotations from the 1889 Pall Mall edition.
“Mister Gazette: Edison, he tells me, has been up for two nights and discovered a “buggy” connection to his One phonograph – a name that solves the problem and hints thatthe angry insect inside has broken free and is only giving him trouble.”
Troubleshooting strategies: I would say identify the source of the problem
One of the perennial mysteries that every Windows user faces at some point in time is how to define a problem as “you won’t see it next time”. This is a feature bug that bothers you for a while and then mysteriously disappears when you need to intervene. (This also often happens when someone asks a neighbor user or someone from the IT department to take care of a problem. Like a car hazard that disappears when your whole family takes the car to a mechanic, a tricky computer problem is often solved once. knowing the person sits down at the keyboard.) When this happens, most people just shake their heads and get on with their work, glad they don’t have to solve the problem anymore >
Unfortunately, most electronic problems are not easy to solve. For these stubborn problems, their main task is to find the cause of the error. At best, this is green art, but in those casesahh, when you use a systematic pattern, you can finish. Over the years, I have found that the best approach is to want to know, a series of questions aimed at gathering the necessary information or determining who might be the culprit. You will study the following sections based on these questions.

TIP
If reporting an error takes you a long time and you can still help other programs on your computer, don’t bother writing all the content. Instead of this while a message is displayed, click “Print Screen”Click on to place an image of the current screen on the clipboard. Then open Paint or another graphic collage maker, paint over most of the screen to give it a new look, and save the image. If you say you’re going to email the image to someone at tech support or someone else can fix it, you should generally save the image as a monochrome bitmap and 16 colors if possible, or as a JPEG file if possible. keep it small for the image period.
