程序代码：

#include <iostream>
#include <iterator>
using namespace std;

int main( void )
{
    size_t buf[100] = {};
    for( size_t value; (cin>>value) && value!=0; )
        ++buf[value-1];

    for( size_t i=0; i!=size(buf); ++i )
        if( buf[i] != 0 )
            cout << (i+1) << "出现" << buf[i] << "次\n";
}
