浅学之变量自增

package operator;

public class Demo01 {
    public static void main(String[] args) {
        //++ 自增  --自减
        int a=5;
        int b=a++;
        System.out.println(a);//a+1
        System.out.println(b);//b=a
        System.out.println("=====================");
        int c=++a;
        System.out.println(a);//a+1
        System.out.println(c);//c=加之后的a

    }
