产生和等于100的5个随机数

题目：随机产生5个数，这5个数每个数的范围都在[10,35]之间，5个数的和是定值100，尽量让5个数的概率随机，写出算法？？

#include <iostream>#include <cstdlib>#include <ctime>using namespace std;void main(){//int i;srand((unsigned)time(NULL));int a,b,c,d,e;a=(rand()%26)+10;b=(rand()%26)+10;if(a!=35&&b!=35){    c=(rand()%26)+10;while((100-a-b-c)/2<10||(100-a-b-c)/2>35) c=(rand()%26)+10;d=(rand()%26)+10;while((100-a-b-c-d)<10||(100-a-b-c-d)>35)d=(rand()%26)+10;e=100-a-b-c-d;}else{c=d=e=10;}cout<<a<<endl;cout<<b<<endl;     cout<<c<<endl;cout<<d<<endl;cout<<e<<endl;system("pause");}
