Write the c++ statements to sort few names using any of the sorting techinques
Answers
Explanation:
Constructing list of names. Declare a vector of strings & take each string &insert to the vector. vector<string>names; for i=0:n-1 input each name; insert name into the vector End for loop.
Sorting in alphabetical order. We can sort the vector using our own comparator function to sort the strings in alphabetical order.
There are two broad types of sorting algorithms: integer sorts and comparison sorts. Comparison sorts compare elements at each step of the algorithm to determine if one element should be to the left or right of another element.
As the name suggests, qsort function uses QuickSort algorithm to sort the given array, although the C standard does not require it to implement quicksort. C++ sort function uses introsort which is a hybrid algorithm. Different implementations use different algorithms.
Yes, it's as you said, and this is not a concept unique to C++. Stable sorts preserve the physical order of semantically equivalent values. std::sort : The order of equal elements is not guaranteed to be preserved.
