第五章第七题（金融应用场景：预测未来的学习费用）(Financial application: compute future tuition)
-
**5.7（金融应用：计算将来的学费）假设今年某大学的学费为10000美元，学费的年增长率为5%。一年后，学费将是10500美元。编写程序，计算10年后的学费，以及从现在开始的10年后算起，4年内总学费是多少？
**5.7(Financial application: compute future tuition) Suppose that the tuition for a university is 10,000 this year and increases 5% every year. In one year, the tuition will be 10,500. Write a program that computes the tuition in ten years and the total cost of four years’ worth of tuition after the tenth year. -
参考代码：
package chapter05;
public class Code_07 {
public static void main(String[] args) {
double money = 10000,sum = 0;
for (int i = 0;i < 10;i++){
money *= 1.05;
if (i < 4)
sum += money;
}
System.out.println("The tuition in ten years is " + money);
System.out.println("The total cost of four years’ worth of tuition after the tenth year " + sum);
}
}- 结果显示：
The tuition in ten years is 16288.946267774418
The total cost of four years’ worth of tuition after the tenth year 45256.3125
