1. 已有的數(shù)據(jù)用過沒有保存好，要用又要重新安裝，重新編程。非常麻煩。
2. 下載源數(shù)據(jù)從這個網(wǎng)站：bstabler/TransportationNetworks
3. net file已經(jīng)轉(zhuǎn)換好了。
4. 下面是OD file
5. 測試成功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.

6. 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.
7. the next case is Winnipeg, 2836 links
   succeed, also I see the memory, 1MB
8. Chicago sketch 2950links
   succeed
   1 MB
9. Austin 18961 links
   6000, 1.3MB
   10000,1.6MB
   12000，1.7
   14000， 1.9
   15000，stackoverflow
   stack 保留
   32768，1000，968kb
   2000，1mb
   3000，1.1mb
   5000， failed
   627680
   5000，1.3MB
   999999
   10000，1.6MB
   999999不是字節(jié)，因為999999byte=976kb，小于1MB
   9999999
   15000，1.9mb
   18961，2.2mb
   succeed
   stack commit 嘗試999999沒用。
10. next is Sydney net
    Sydney net has 75379 links
    9999999 7
    1000, 992kb
    5000，1.2MB

    70000,5.7mb
    75000,6.1mb
    75379,6.1mb,5500000
11. Sydney net 完成輸入
    怎么調(diào)堆棧？屬性，連接器，系統(tǒng)，保留大小。
12. 75379 link，6.1mb，至少安排5500000的?？臻g。
