代码

//range.cpp

#include <stdio.h>
#include <iostream>
#include <string>

using std::cout;
using std::endl;
using std::string;

    int min;
    int max;
    char s[]={'\0'};
    const char *pref=s;
    const char *tail=s;

    if (argc<3) {
        cout<<"usage: range min max [pref] [tail]"<<endl;
        cout<<"usage: range min max [spector]"<<endl;
        return 0;
    }

    sscanf(argv[1], "%d",&min);
