一个C程序的问题，现在是输出最大字符串，要求改成可以将两个字符串连接起来。具体请参

程序如下：#if !defined(__STRNG_H )#include<string.h>#endif  // __STRNG_H #ifndef__IOSTREAM_H#include<iostream.h>#endif //// Determines themaximum string using the ASCII collating sequence to // definerank.  A string is defined to be greaterthan another if the// ASCII values ofits characters are greater than the values of the other// string.  For example,//// strngmax AlphaBeta Charlie//// would printCharlie to stdout and return 3.//int main( intargc, char *argv[] ){    if( argc < 2 )        {        cerr << "Usage:  strngmax string1 [string2 ...]\n";        return 1;        }     char *theGreatestString( argv[1] );    int positionOfTheGreatestString = 1;    int nextArg = 2;     while( nextArg < argc )        {        char *argListString ( argv[nextArg++]);        if ( argListString >theGreatestString )            {            theGreatestString = argListString;            positionOfTheGreatestString = nextArg -1;            }        } cout << theGreatestString << endl;     return positionOfTheGreatestString;}
以上程序输入 strngmax 1234 3456 ，则可以得出结果3456那么现在要修改成输入 strngmax 12345 67890 。则得到结果1234567890如果能够给出方法的大致解析我将不胜感激！再追加20分！
