C语言main函数传递参数

如下：

void main(int argc, char **argv)
{
	for (int i=1; i<argc; i++)
	{
		printf("%s	", argv[i]);
	}
	printf("\n");

	if (argc - 1 != 2) // 如果传进来的参数不是2个，则赋值之
	{
		argc = 2 + 1;
		argv[1] = "file1.txt";
		argv[2] = "file2.txt";
	}


	printf("********************************\n");


	printf("=====end=====\n");


	system("timeout /t 60");
}
