It is normal for a programmer to encounter a problem especially if you are new in the industry. If you are faced with a challenge, it could be one of the few that will be mentioned below.
Setting up- leaning how to program takes awhile so when you begin, you obviously need to choose a programming language. Professionals would normally recommend C++. Computers only work when you tell it to. So the setting up process must be detailed. Remember, computers already have pre-existing functionality. Other functions that you want to happen, you need to be doing yourself.
Do not freak out about error messages. A single mistake can cause the compiler to get confused and will then generate error messages. When this happens, you need to go back from the beginning to figure out what you did wrong. You will get used to these compiler error messages and learn the ropes as you get by.
