What is vector sorting?

Sorting a vector in C++ Sorting a vector in C++ can be done by using std::sort(). It is defined in header. It is exactly like sort() but maintains the relative order of equal elements.

It is an matrix implemented with the help of vectors. Case 1 : To sort a particular row of 2D vector. This type of sorting arranges a selected row of 2D vector in ascending order . This is achieved by using “sort()” and passing iterators of 1D vector as its arguments.

For example, you could use a lambda function: std::vector> vec; // Fill it std::sort(vec. begin(), vec. end(), [](const std::vector& a, const std::vector& b) { return a[2] < b[2]; });

​ The value of angle fuction for a particular angle of a vector must be greater than the other vector. ​ ​ ​Vector which has greater value of product of magnitude and value of angle function.

By default the sort function sorts the vector elements on basis of first element of pairs. Case 2 : Sorting the vector elements on the basis of second element of pairs in ascending order. There are instances when we require to sort the elements of vector on the basis of second elements of pair.

This type of sorting can be achieved using simple “ sort() ” function. By default the sort function sorts the vector elements on basis of first element of pairs.

To accomplish sorting we are going to use the algorithm ‘sort’ from the standard library (requires to #include ). The default version of ‘sort’ takes two arguments – the iterator to the initial and final position of a sequence to be sorted.

Every vector of integers as an element of “big” vector has 4 INT values. I want to sort vec basing on third value of it’s content vectors of ints (I mean every “inside” vector third element) – is it possible?
