#include
int prime(int n)
{
    int j=2;
    while(n%j!=0)
        j++;
    if(j==n)
        return 1;
    else
        return 0;
}
void main()
{
    while(1)
    {
    int i,p,k,m;
    cout<<"请输入一个2-10000的整型数:";
    cin>>i;
    m=i;
    if(!prime(i))
    {
        cout<<"i=";
        for(p=2;p<I;P++)
        {
            if(prime(p))
            {
                k=0;
                while(i%p!=0)
                {
                    m=m/p;
                    k++;
                }
                switch(k)
                {
                case 0: break;
                case 1: cout<<P;
                    if(!prime(m))
                        cout<<"*";
                    break;
                default :cout<<P<<"^"<<K;
                    if(!prime(m))
                        cout<<"*";
                }
            }
        }
        cout<<ENDL;
    }
    else
        cout<<I<<ENDL;
    }
}

弄错了 应该是
while(i%p==0)
     {
          m=m/p;
          k++;
     }
就是老师出了一道题：输入2-10000中任一数使其输出结果为：2=2 3=3 4=2^2 5=5 6=2*3 7=7 8=2^3 9=3^2 10=2*5……    请问我这个程序哪个地方不对啊

         谢谢了  ！
