teach you different ways to reverse an array in C#, including predefined methods. Generally it requires the creation of atempvariable to store the first index value of an arraytemp = arr[0], store the second index value inarr[0]likearr[0] = arr[1], and store thetempvalue inarr[1]....
Alternatively, to reverse the array elements in place without declaring other variables, we can call thestd::reversefunction from the standard library.std::reverseis part of the<algorithm>header and has been part of the standard library since the C++17. The function takesstart/enditerators of th...

Create an array of type double that can hold up to 5 elements. Ask the user for 5 numbers. Display those numbers in the reverse order from which they were entered. Note: this assignment must use loops. I should be able to change a single variable from 5 to 10 and have it work corre...
Reversing an array in PHP is an easy operation done by the built-in functionarray_reverse(). This built-in function can reverse an array’s elements, including the nested arrays. Thearray_reverse()also provides functionality to preserve the key elements according to the user. This built-in ...
