問題：
下載的開源代碼按照要求格式輸入檔案后，就提示“按任意鍵繼續。。。”，或者cmd命令窗直接就自動退出了。
具體：
設定斷點單步除錯發現，程式應該是沒讀到我的輸入命令列，argc=1直接按照程式輸出文字就直接退出進行了，細看代碼感覺很奇怪，這是一個很老的模型，內部代碼因該是肯定沒錯的，不需要修改，不知道哪里出問題了。代碼段如下：
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
#include <string.h>
#include "config.h"
#include "tMCimg.h"
#include "mccore.h"
#define USAGE printf("options: if string contains...\n"\
"\t? - display the option help (this)\n"\
"\tn - inhibit .2pt file storage and dump\n"\
"\tR - Use normal C ordering for segmentation/.2pt files\n"\
"\ts - don't move sources to the boundary\n"\
"\td - don't move detectors to the boundary\n"\
"\tt - write exact exit time to .his.t instead of tgate # to .his\n"\
"\tm - make tissue-air boundaries perfectly mirrored\n\n")

if (argc == 1)
{

printf("\tSources %s to interface\n",

printf("\tMirrored air boundaries\n");
printf("\n");
getchar();
return 1;
}
這段代碼最后的getchar();是我后加上去的，要不然命令窗就會一閃而過，不給輸入檔案的機會。
單步除錯程式運行到return 1;就會跳出整個int，退出行程結束運行了。
但正常這個程式運行程序應該是讀取我輸入的字串然后進行下面的程式，現在是根本沒進入程式就結束了，實在搞不懂了，求路過大神。
后面的程式是這樣的，我沒有看懂他那里識別我輸入的命令列
