各位大神,帮小弟看看怎么老是不对呢?#include <stdio.h> int getprime(int a) { int i,j,count=1,flag,b[666],sum=0,k=0; b[0]=2; for(i=3;i<a+1;i++) //找到小于等于a的所有质数,并放在数组b中 { flag=0; for(j=2;j<i;j++) if(i%j==0) { flag=1; break; } if(flag=0) { b[count]=i; count++; } } for(i=0;i<count;i++) //找出能代替a的表达式的个数 { sum=b[i]; for(j=i;j<count;j++) { if(sum==a) { k++; break; } else { if(sum<a) { j++; sum=sum+b[j]; } else break; } } } return k; } int main() { int a,c[10],k; int i; for(i=0; ;i++) { scanf("%d",&a); if(a!=0) { c[i]=getprime(a); k=i+1; } if(a==0) break; } for(i=0;i<k;i++) printf("%d\n",c[i]); } Followed by: Post your reply here: |
