命令format rat, 0.5输出的结果是（） A: ans=0.5000 B: ans=1/2 C: ans=+ D: ans=0.50

考查下面的程序代码： int num1=40; int num2=5; int ans=0; if(num1/5==num2) {ans=10; } if(num2%5==0) {ans=20; } if(num2==0) {ans=30; } else {ans=40;} System.out.println("answer is:" + ans); 下面哪个是程序的输出结果：

What will be the values of ans, x, and y after the following statements are executed?执行以下语句后，ans，x和y的值是什么？int ans = 35, x = 50, y =50;if ( x >;= y){ans = x + 10;x -=y;} else {ans = y + 10;y += x;} A: ans = 60, x = 50, y =100 B: ans = 60, x =0, y =50 C: ans = 45, x = 50, y = 0 D: ans = 45, x = 50, y = 50

What will be the values of ans, x, and y after the following statements are executed? int ans = 35, x = 50, y =50; if ( x >= y) { ans = x + 10; x -=y; } else { ans = y + 10; y += x; }

What will be the value of ans after the following code has been executed? int x = 90, y = 55, ans = 10; if ( x == y); ans *= 2;

已知ans='y'，则表达式ans=='y' or 'Y'的值为________________________。
