How to display the sum of the cubes of the digits?
提问by name123
Code:
代码：
import java.util.*;
import java.io.*;
class Cubesum {
public static void main(String args[]){
int input=0;
int num1,num2,num3;
//read the number
System.out.println("Enter a Number");
Scanner console = new Scanner(System.in);
input= Integer.parseInt(console.nextLine());
// now let us print the cube of digits
//i.e if number is 123 we will print 1^3, 2^3 and 3^3
//we will also add 1 and 3 to output the sum of first
//and last digits
int number = input; //number is a temp variable
int counter = 0; //counter is used to count no of digits
while(number>0){
int t= number%10;
System.out.println("Cube of "+t +" is "+(t*t*t));
counter = counter+1;
number = number/10;
}
}
}
Output:
输出：
Enter a Number
**223**
Cube of 3 is 27
Cube of 2 is 8
Cube of 2 is 8
How do I add the cubes of these numbers? For example, 27+8+8 would be 43
我如何添加这些数字的立方体？例如，27+8+8 就是 43

Maybe you want to do something like this:
也许你想做这样的事情：
int number = input;
int sum = 0;
while (number > 0) {
int digit = number % 10;
sum += digit * digit * digit;
number /= 10;
}

Here a solution:
这里有一个解决方案：
int sum = 0;
while(number>0){
int t= number%10;
System.out.println("Cube of "+t +" is "+(t*t*t));
sum += t*t*t;
counter = counter+1;
number = number/10;
}
System.out.println(sum);

You seem new to Java, so here is a more simple (and readable) example for you:
您似乎对 Java 不熟悉，因此这里有一个更简单（且可读）的示例：
import java.util.*;
import java.io.*;
class Cubesum {
public static void main(String args[]){
int num1,num2,num3;
Scanner console = new Scanner(System.in);
//read the numbers
System.out.println("Enter the first number");
num1 = Integer.parseInt(console.nextLine());
System.out.println("Enter the second number");
num2 = Integer.parseInt(console.nextLine());
System.out.println("Enter the third number");
num3 = Integer.parseInt(console.nextLine());
int output = (int1*int1*int1)+(int2*int2*int2)+(int3*int3*int3)
System.out.println("result is: " + output);
}
}
You want to get each number individually then create the result.
您想单独获取每个数字，然后创建结果。
Sample input:
样本输入：
2
2
3
Output should be:
输出应该是：
43

Try this code.
试试这个代码。
int sum=0;
while(number>0){
int t= number%10;
System.out.println("Cube of "+t +" is "+(t*t*t));
sum=sum+(t*t*t);
counter = counter+1;
number = number/10;
}
System.out.println(sum);
