C语言程序设计教程（第三版）课后习题6.5 （Java代码）

解题思路:





注意事项:





参考代码:

import java.util.Scanner;

public class C1015 {

public static void main(String[] args) {

Scanner scanner = new Scanner(System.in);

while (scanner.hasNext()) {

int a = scanner.nextInt();

int b = scanner.nextInt();

int c = scanner.nextInt();

double result = function(a, b, c);

System.out.println(String.format("%.2f", result));

}

scanner.close();

}

private static double function(int a, int b, int c) {

double sum = 0;

for(int i = 1; i <= a; i++){

sum += i;

}

for(int i = 1; i <= b; i++){

sum += i*i;

}

for(int i = 1; i <= c; i++){

sum += 1.0/i;

}

return sum;

}

}
