argv简单应用

命令行使用

// test.cpp : 定义控制台应用程序的入口点。
//

#include "stdafx.h"
#include <iostream>
using namespace std;

int _tmain(int argc, _TCHAR* argv[])
{
 int i=0;
 while(argv[i])
  cout << argv[i++] << " ";
 cout<<endl;
 cout << "argc=" << argc << endl;
 cout << "i=" << i << endl;
 cout << "argv[]:" << *(argv[0])<< endl;
 getchar();

 char * pFilePath = argv[1];//作用等价，只是要在命令窗口输入，此处argv[0]默认是test.exe
 
 char sFilePath[255] = {0};
 memcpy(sFilePath,"E:\\test\\test.txt",strlen("E:\\test\\test.txt")); 
 //strncpy(sFilePath,"E:\\test\\test.txt",strlen("E:\\test\\test.txt"));
 return 0;
}
