为什么还是wrong answer?难道fun部分有问题?我下午在UNIX上调过的,现在凭记忆写出来(只把原来int b[150]改为short了),难道写错了?不会啊!大家帮忙看一下,谢谢! void fun(float a,int n) { long al,temp1,temp2; short b[150]={0}; /*存放结果的数组*/ int i,j,k=0; short *p;p=b; while(a!=(float)((int)a)) /*把a转为long型,存为al,并求小数位数k*/ {a*=10;k++; } k=k*n; /*n次方的小数位数*/ al=(int)a; b[149]=1; for(i=0;i<n;i++) { temp2=0; for(j=149;j>=0;j--) { temp1=b[j]*al+temp2; /*求某位数乘以al后再加后一位进位进上来的数*/ b[j]=temp1%10; temp2=temp1/10; /*往前进位的数*/ } } while(*p==0&&p<b+149-k) p++; /*处理掉前面多余的0*/ for(;p<b+150-k;p++) printf("%d",*p); printf("."); for(;p<b+150;p++) printf("%d",*p); } main() {float a;int n; while(scanf("%f%d",&a,&n)==2) { fun(a,n);} } Followed by:
