Lambda expression in c++11

Lambda expression writing format in C + +

[capture list] (params list) mutable exception-> return type { function body }

The list of external variables, which is the list of capture list params list function parameters, mutable can be modified by external variables, exception exceptions, and return type return types.

Later, the sort can be written like this.

/*以下代码摘自陈锋的《紫书解答》*/struct TS {    int a, b, c;}tss[N];sort(tss, tss+N, [](const TS& t1, const TS& t2) {        if (t1.a != t2.a) return t1.a < t2.a;        if (t1.b != t2.b) return t1.b < t2.b;        return t1.c < t2.c;    });
