Programming can be a complex process,it requires trainings,plannings,and some specialized tools along programming examples and tutorials at the same time.If you think this task sounds like any other construction process, you are right;creating a software program is like building an office building or shopping center.You have to study the market,create a plan,hire a crew,get special tools,and then finally build the building.But the work does not stop here.You must continually update your creation to meet the changing needs of the people who use it.

Successful programmers are knowledgeable in two keys areas programming tools (the softwares and languages used to develop applications) and the programming process(the step by step procedures that the programmers follow to ensure the consistent ,well developed products). Software developers of all  backgrounds and in many different working environments follow a uniform set of procedures in their work.Thus ,programmers can work together more easily on large projects and they can accurately predict how their programs will work.
