随机选题cprogram帮忙

angelineang

我想要把我的quiz 设为random，我用了srand（）和rand（）但是我不懂怎样把他们放进去题目中，真的很乱，有谁可以帮忙吗？
srand ( time(NULL) );
for (int i=0;i<=10;i++);
{
question= rand () %20 + 1;
printf("\n%d",i+1);

你用PHP还是ASP.NET？

可以试试看array,或io text file
记得random出来的号码要compare之前的,不然问题会重复

你的 coding 只有一小部分，無法明白放進題目的意思

接下去都是一样的重复10次，可是好像没有用的感觉

    如果我是用while或if else的呢？
好像我rand出来的号码是2的话就写
if
（quizquestion=2）；
quizquestion2（）；//我在这边是call function的//
