The necessary information for software developers

By: Mathew Petrenko

Programmer utilities is the detached class of soft that is intended for being used during the action of planning, development and debugging of programs. This term is commonly used to distinguish that kind of software from application oriented and system programs. One of the most important stages of creating the modern software is creating the installation system for this product. The earlier family of software didn't have any complexities with installation. The user had to move the files to any directory of the hard disk. MS-DOS didn't require any additional procedures. If the program was compatible with the equipment, it operated correctly. Nowadays any software designer must realize that to make a successful software program he has to use the special soft named installer tools. That is the class of software which can help to install any files, such as application, drivers, etc. on the PC. Some installers are created for installing the files included inside of it, others are considered to be universal and they operate reading the substance of the package of the programming software, that needs the installation. Windows OS has got lots of beauties. One of them is that the action of installation became simpler than it used to be in MS-DOS. The product includes the row of instructions which have to be carried out in the given sequence. This algorithm has to be transformed into the programming language.

Modern software products are quite big so they can't be included into the one file. That's why there is a problem how to develop the correct access system for all the files that belong to this program. Frequently they are placed in some number of files that can be located even on several different information carriers. In such cases the usage of special additional installation software is truly essential. No other actions are required, excepting the process of installation for the right usage of the program which is compatible with Windows OS. The necessary data about the hardware features will be automatically got by the installer. The final phase of designing any modern program is debugging, that helps to detect, restrict and correct all the mistakes. As the main means of the debugging the debug programs should be utilized. Step performance of the program is the principal idea of any debugging action. Operation by operation, function by function the program is run and it is stopped when reaching needed line of the initial code or if the definite condition is reached. All the values of constants are shown for the programmer in the debug mode. Debugging is very hard and exhausting action. The action of debugging is simpler if the product was designed utilizing such programming language as Java that includes the special tool called exception handling. Origins of the complexity can be simply found if the programmer uses such software. If such programming languages as C or assembler are used, not all the problems can be detected during the action of testing the program. For instance, it could be the injury of memory or the memory ooze. These problems can be found only by means of utilizing different additional debugging software.
