程序代码：struct Number
{
int start;
int end;
int middle;
};
vector<Number> group;
{
int start;
int end;
int middle;
};
vector<Number> group;
请问怎么样能把这个vector按照Number.middle的大小来排序？
程序代码：bool comp(Number &n1, Number &n2);
{
return n1.middle > n2.middle;
}
sort (group.begin(), group.end(), comp);
{
return n1.middle > n2.middle;
}
sort (group.begin(), group.end(), comp);
我试了一下貌似不行……
