题:
反复滚动3个骰子,直到双打滚动(任何两个是相同的).每次显示值,然后显示获得双打所需的尝试次数.
我的代码:
#include <iostream>
#include <time.h>
#include <stdlib.h>
#include <string.h>
using namespace std;
int main ()
{
srand (time(NULL));
int j=1;
int i=0;
int a;
int b;
do
{
int a=(rand ()%6+1);
int b=(rand ()%6+1);
cout<<a<<" and "<<b<<endl<<endl;
j++;
}
while (a!=b);
cout<<"They are the same!"<<endl<<endl;
cout<<"It took "<<j<<" tries.";
return 0;
}

问题:
循环不会停止.即使a和b相同,程序也不会停止.
