First, learn to use programming to develop software. Sharp tools can do a good job. If we want to develop a software, we must use some advanced languages, such as C, C++, VB, PHP and so on. We must learn to use their programming methods (the use of software) before we can develop software easily. Second, think in a programmed way. Computers are different from people. We humans can think, but computers can't. They can only operate according to our programmed instructions. If we want to make a program, we must think in a procedural way. For example, when we walk at ordinary times, if we want to go up a step, we can naturally cross it. Program-controlled robots are different. It needs to calculate the height of the steps, the height and amplitude of its own feet, and then calculate how far it has to go before it can cross the next step. So if we want to make a good program, we must have the ability to think with the program. Many things that we think are easy, the program has to calculate many times to achieve. Third, solve practical problems. We study computers only to solve practical problems. In real life, many difficult problems can be solved by computers. For example, if a teacher ranks students manually, it is necessary to list each student's grades, calculate the average score and total score, and finally rank them one by one. The process is boring and takes a lot of time. Let's leave the ranking to the program, just for a moment. Computers can save us from those boring things. Fourth, don't just think about developing software. We should use other people's software more and absorb their advantages. More use of software will make us have more and better ideas, and many new things are produced from old things. For example: chat software. Online chat software, such as QQ, is transformed from old things (before online chat software appeared, people mostly communicated through website messages and forums). The more we want to develop software, the less we know what to do. Many good softwares are produced to solve practical problems.
