Computer major has always been a hot major in college entrance examination. As long as this major has good mathematical thinking, learning computer is a very good choice. At least being a programmer is also a very high-paying position. There are many "higher" development directions, such as artificial intelligence, machine learning, information security attack and defense. Whether entering a scientific research institution or enterprise research and development, it is the starting price with an annual salary of several hundred thousand.

More importantly, the cost of learning computers in this era is very low, and we can start with a computer. When you are in a bad mood, you can live a carefree life even if you quit your job, develop a small program and code yourself. It should be emphasized that computers and mathematics are closely related. Students who want to do a big job in this field will gain a very favorable advantage if they devote themselves to mathematics during their freshman and sophomore years.
