有如下程序：
public class Sun

public static void main(String args[ ])

int s=0;
int i=1;
while (i＜=100)

s=s+i;

System.out.println(s);

运行后的结果是( )。

A．5050

B．5051

C．死循环，直到溢出

D．无穷大的数

答案

参考答案：C

解析：本题考查对while循环语句的理解。在while语句中的条件再循环中必须有加的可能，循环才能正常结束。如条仆恒为真，循环水无终止地进行下去，出现死循环。此程序由于i的值始终小于0，因此，这是一个死循环， s的值为1+1+1+...直到系统溢出。如在第4行后面加上语句i=i+1，循环就会正常结束。故本题答案是C。
