Re:改后代码...In Reply To:怎么老错了? Posted by:acm_bug at 2006-10-04 09:02:21 #include<iostream> using namespace std; int b[10000]; int main() { int a,c,i; memset(b,0,10000); for(i=0;i<10;++i) { cin>>c; a=c; if(a==2)b[2]++; else if(a==3)b[3]++; else if(a>=4) for(int j=2;j<=c;++j) { while((a%j)==0) {a/=j;b[j]++;} if(a==1)break; } } int num=1; for(i=0;i<10000;++i) {if(b[i]) num*=(b[i]+1);num%=10;} cout<<num<<endl; getchar(); return 0; } 貌似这个程序G++编译效率会高些...
