一个奇异的程序(G++可过)以下程序我原来没用long long,而是用了int和unsigned int,结果在Debug底下答案是对的,在Release底下i>189414495时答案错的离谱(N多0)。后来用了long long,用G++可以AC,但是C++就Compile Error.问哪位大虾可以将其小改一下使其用C++可以AC?? #include<iostream> using namespace std; int main() { long long a[5]={0,45,9045,1395495,189414495}; long long b[6]={0,1,11,192,2893,38894}; long long c[6]={0,1,10,100,1000,10000}; long long n,i; for(cin>>n;n>0;n--) { cin>>i; long long j; for(j=1;i>a[j];++j); //判是几位数 i-=a[j-1]; long long s=b[j],f=c[j]; for(;i>s;++f) s+=b[j]+(f-c[j]+1)*j; long long t=s-i; for(;t>0;--f,t-=j) if(f<c[j])j--; if(t!=0){ f+=1; if(f>c[j]*10-1)j++; t+=j; for(;t!=0;--t,f/=10); } cout<<f%10<<endl; } } Followed by:
