- 已有的数据用过没有保存好，要用又要重新安装，重新编程。非常麻烦。
- 下载源数据从这个网站：bstabler/TransportationNetworks
- net file已经转换好了。
- 下面是OD file
- 测试成功fopen_s and fscanf_s的用法
FILE *fp1, *WriteFile;
errno_t err,err2;//*difference
//difference is: err=fopen_s(&fp1....!=0
//critical: !=0
if ((err = fopen_s(&fp1,"C:\\net.txt", "r")) != 0) {
printf("can not opennet.txt");
getchar();
return;
}
int a = 0;
// fscanf_s....
fscanf_s(fp1, "%d", &a);
printf("%d\n",a);
C:\TEST\SourceNet\, put in the deeper folder, succeed
1 2 25900.20064 6 6 0.15 4 0 0 1 ;
input only one line, succeed
input two lines, succeed.
output is also succeed.
test the siouxfalls is also succeed.
test the whole 76 links, succeed.
so, the whole code is saved.
- SixousFalls completed, the next case is Anaheim
we just need to set a parameter: how many links are there
and change the file name
succeed. - the next case is Winnipeg, 2836 links
succeed, also I see the memory, 1MB - Chicago sketch 2950links
succeed
1 MB - Austin 18961 links

怎么调堆栈？属性，连接器，系统，保留大小。 - 75379 link，6.1mb，至少安排5500000的栈空间。
