How to sort vector in descending order in stl
WebTo sort the data in descending order we need to make use of the binary predicate function as a third parameter of the sort function in C++. In the following code example, we used the greater function which is used to perform the comparison, it helps to sort vector in the descending order. Code Example: WebSort Array in Descending Order in C++ using STL’s std::sort () The sort () function mainly accepts three arguments. First one is the starting address position and second one is the last address position of the array which need to be sorted. The third optional argument can be passed to determine the sorting order.
