digsum3.java

JAVA用函数实现四则运算

public class Digsum3	
{
    public static void main(String args[])
    {
        int n=123,a=0,b=0,c=0,digsum=0;
        a = n % 10;           //个位
        b = (n%100) /10;      //十位
        c = n / 100;          //百位
        digsum=a+b+c;
        System.out.println("Digsum("+n+") = "+digsum);
    }
}
