(A) and (C) are the same
(A) and (B) are the same
(B) and (C) are the same
D: (A), (B), and (C) are the same
A: x -= x + 4
B: x = x + 4 - x

- 下面程序的运行结果是(<br/>)。 int fun (int x,int y) { x=x+y; return(x);}int main( ) { int x=2,y=4; y=fun (x,y); printf("x=%d y=%d\n", x, y);} A: x=2<br/>y=4 B: x=2<br/>y=6 C: x=6<br/>y=6 D: x=6<br/>y=4
- 不等式|2x-3|>5的解集是( )() A: {<br/>x|x4} B: { x|-1 C: { x|x D: {<br/>x|x>4}
- 以下代码将显示什么?[br][/br]x = 1[br][/br]x = 2 * x + 1 [br][/br] print(x) A: 3 B: 0 C: 1 D: 2 E: 4
