#include <iostream>
using namespace std;
int main( int argc, char *argv[], char *env[])
{
cout << "Program: " << argv[0] << endl;
cout << "Command line arguments:" << endl;
int i;
for( i = 1; i < argc; ++i)
cout << argv[i] << endl;
cout << "Type <Return> to go on";
cin.get();
cout << "Environment strings:" << endl;
for( i = 0; env[i] != NULL; ++i)
cout << env[i] << endl;
return 0;
}
结果为:输出程序编译生成的exe文件的路径和运行参数,然后点击回车后,输出环境变量.
