Vector-Sort
You are given integers.Sort the integers and print the sorted order.
Store the integers in a vector.Vectors are sequence containers representing arrays that can change in size.
· Declaration:
· vector<int>v; (creates an empty vector of integers)
· Size:
· int size=v.size();
· Pushing an integer into a vector:
· v.push_back(x);(where x is an integer.The size increases by 1 after this.)
· Popping the last element from the vector:
· v.pop_back(); (After this the size decreases by 1)
· Sorting a vector:
· sort(v.begin(),v.end()); (Will sort all the elements in the vector)
