code in C language to simulate population changes. The initial population is 100,000, and the initial age distribution of the population is evenly distributed between 20 and 60 years old. The initial employment rate of the population is 100%. AI will impact the employment rate of this group of people after several years. The employment rate for the children of this group remains constant. People aged between 30 and 45 will have 1.1 children, and they will work until the age of 70, with the death age set at 95. If a person has no job for 30 years and is under 70 years old, they will die. Newborns will randomly die with a 50% chance if they do not have a job for 40 years. The question is how many people will remain after 200 years.
