How to make a computer program

...ving the ability to analyze is the chief skill that a programmer should learn. Designing can be more creative, not just like "A mouse only can left-click, right-click and move". If we restrict in these functions only, a wheel mouse must not be realized now. This leads to the second ability of a programmer, which is creativity. Writing is the heart in the programming; we spend lots of time designing because of writing the codes! A program is full of Variables Operation and Control Structures; we will find it easy to watch the program source when we know the code's meaning and the logic it uses. Let's to introduce what is Variables Operation and Control Structures. Do you remember addition, subtraction, multiplication and division? These are the math operation in the Variables Operation; we will use in symbols like " +-*/ ". In math operation, it also have " % ", it means modulus. For example, 7%2 is 1, 5%3 is 2. The other operations are used to be control the variables, which can stick two words together. Every computer language should have lots of own function; these functions also can help us to control the variables. Control Structures is like a logic maker. "A statement can be an assignment, a function call, a loop, a conditional statement of even a statement that does nothing (an empty statement). " (PHP, Oct 1, ) No matter what computer language we learn, it must have this statement: If. For example, "If the 'a' key pressed down, the 'a' will display on the screen.¡¨ "The 'a' key pressed down" is the condition, "the 'a' will display on the screen" will be run when the condition is return true. Of course, writing codes is the greatest important part in the programming; we will use a lot of functions and statements. Every programmer cannot to remember all of these things, so they will make a function list or download a function list from the Internet, and find functions in the list like to find words in the dictionary when they are writing codes.
