Question

为何该C++程序无限循环？

temp1=1;
j = s-1-(((i/2)-1)*2);
while (temp1 <= i)
cout << j << endl;
temp1=temp1+1;
j=j+2;

Answer 1

while (temp1 <= i)
{
cout << j << endl;
temp1=temp1+1;
j=j+2;
}

Answer 2

temp1=1;
j = s-1-(((i/2)-1)*2);
while (temp1 <= i) 这个while没加大括号
就只执行后面的一条
cout << j << endl;
temp1=temp1+1;
j=j+2;
