作业

第一题:
看程序说答案
int a = 10;
int b = 3;
int c = a + b; //c=? 13
int d = a - b; //d=? 7
int e = a * b; //e=? 30
int f = a / b; //f=? 3
int g = a % b; //g=? 1
a++;//a=? 10
++a;//a=? 11
b--;//b=? 3
--b;//b=? 2

第二题:
看程序说答案
int a = 10;
a += 2; //a=? 12
a -= 3; //a=? 9
a *= 4; //a=? 36
a /= 5; //a=? 7
a %= 3; //a=? 1
第五题:
看程序说结果，注意不要提前运行代码。
public class Test {
public static void main(String[] args) {
short s = 30;
int i = 50;
s += i;
System.out.println("s="+s); 80
int x = 0;
int y = 0;
int z = 0;
boolean b;

		b = x>0 && z++>1;
		x++;
		System.out.println("b="+b); false
		System.out.println("z="+z);  0

		b = x>0 || z++>1;
		System.out.println("b="+b); ture
		System.out.println("z="+z); 0
	}
}
