一组简单的计算题:
int i=0 ,j=0;
int a=0, b=0;
请计算: i = i++ 求: i=?
a = i++ i=?,a=?
j = ++j j=?
b = ++j j=?,b=?
测试用例:int a=0, b=0;
请计算: i = i++ 求: i=?
a = i++ i=?,a=?
j = ++j j=?
b = ++j j=?,b=?
int i=0 ,j=0,k=0,p=0;
int a=0, b=0;
Response.Write("i的初始值是:" + i.ToString());
i = i++;
Response.Write("=======算式(i=i++)=========");
Response.Write("计算后的i是:" + i.ToString() + "\r\n");
Response.Write("<br>");
Response.Write("k的初始值是:" + k.ToString());
a = k++;
Response.Write("======算式(a=k++)========");
Response.Write("计算后的a是:" + a.ToString() + ";计算后的k是:" + k.ToString() + "\r\n");
Response.Write("<br>");
Response.Write("j的初始值是:" + j.ToString());
j = ++j;
Response.Write("=====算式(j=++j)========");
Response.Write("计算后的j是:" + j.ToString() + "\r\n");
Response.Write("<br>");
Response.Write("q的初始值是:" + p.ToString());
b = ++p;
Response.Write("=====算式(b=++p)========");
Response.Write("计算后的b是:" + b.ToString() + ";计算后的p是:" + p.ToString() + "\r\n");
Response.Write("<br>");
int a=0, b=0;
Response.Write("i的初始值是:" + i.ToString());
i = i++;
Response.Write("=======算式(i=i++)=========");
Response.Write("计算后的i是:" + i.ToString() + "\r\n");
Response.Write("<br>");
Response.Write("k的初始值是:" + k.ToString());
a = k++;
Response.Write("======算式(a=k++)========");
Response.Write("计算后的a是:" + a.ToString() + ";计算后的k是:" + k.ToString() + "\r\n");
Response.Write("<br>");
Response.Write("j的初始值是:" + j.ToString());
j = ++j;
Response.Write("=====算式(j=++j)========");
Response.Write("计算后的j是:" + j.ToString() + "\r\n");
Response.Write("<br>");
Response.Write("q的初始值是:" + p.ToString());
b = ++p;
Response.Write("=====算式(b=++p)========");
Response.Write("计算后的b是:" + b.ToString() + ";计算后的p是:" + p.ToString() + "\r\n");
Response.Write("<br>");
得出的结果:
i的初始值是:0=======算式(i=i++)=========计算后的i是:0
k的初始值是:0======算式(a=k++)========计算后的a是:0;计算后的k是:1
j的初始值是:0=====算式(j=++j)========计算后的j是:1
q的初始值是:0=====算式(b=++p)========计算后的b是:1;计算后的p是:1
k的初始值是:0======算式(a=k++)========计算后的a是:0;计算后的k是:1
j的初始值是:0=====算式(j=++j)========计算后的j是:1
q的初始值是:0=====算式(b=++p)========计算后的b是:1;计算后的p是:1
