我在所有函数之外编写了这段代码:

int l, k;
for (l = 1; l <= node; l++)
{
    for (k = 1; k <= node; k++)
    {
        flow[i][j] = capacity[i][j];
        flow[j][i] = 0;
     }
}

它在编译时给出了以下错误:

shalini@shalini-desktop:~$ g++ -o output fords.cpp
fords.cpp:63: error: expected unqualified-id before ‘for’
fords.cpp:63: error: expected constructor, destructor, or type conversion before ‘<=’ token
fords.cpp:63: error: expected constructor, destructor, or type conversion before ‘++’ tok

如果我们有数百万个大小从几 KB 到几 MB 不等的小文本文件，那么 HDFS 和 HBASE 中的哪一个需要更少的处理时间？而且内存消耗更少？
