How do you sort an array in descending order?

C Program to Sort the Array in Descending Order

  1. Create an array of fixed size (maximum capacity), lets say 10.
  2. Take n, a variable which stores the number of elements of the array, less than maximum capacity of array.
  3. Iterate via for loop to take array elements as input, and print them.
  4. The array elements are in unsorted fashion, to sort them, make a nested loop.

How does array sort work?

The sort() method allows you to sort elements of an array in place. Besides returning the sorted array, the sort() method changes the positions of the elements in the original array. By default, the sort() method sorts the array elements in ascending order with the smallest value first and largest value last.

How do you sort a string array?

How do I sort an array in PHP?

PHP Sorting Arrays

How do you sort an array in C++?

How to sort in descending order? sort() takes a third parameter that is used to specify the order in which elements are to be sorted. We can pass “greater()” function to sort in descending order. This function does a comparison in a way that puts greater element before.

Which sorting algorithm is best?


How do you bubble sort an array in C++?

To sort an array in ascending order using bubble sort in C++ programming, you have to ask from user to enter the array size and its elements. Now start sorting the array elements using the bubble sort technique and display the sorted array on the screen as shown here in the following program.

How do you reverse an array sort in C++?

To sort an array in reverse/decreasing order, you can use std::sort algorithm provided by STL. It sorts the elements of a container in the range pointed by the specified iterators using a comparator. The default comparator used is std::less which sorts the container in ascending order using operator< .

How do you reverse an array?

Algorithm to reverse an array

  1. Input the number of elements of an array.
  2. Input the array elements.
  3. Traverse the array from the last.
  4. Print all the elements.

Is there any sort function in C?

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.

How do you sort an array in Python?


  1. STEP 1: Declare and initialize an array.
  2. STEP 2: Loop through the array and select an element.
  3. STEP 3: The inner loop will be used to compare the selected element from the outer loop with the rest of the elements of the array.
  4. STEP 4: If any element is less than the selected element then swap the values.
