Thearray_reverse()also provides functionality to preserve the key elements according to the user. This built-in function will take an array as a parameter and return the reversed array. The syntax for this method is: arrayarray_reverse($Input_Array,$Key_to_Preserve) ...
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...

The type describes an object that can serve as a reverse iterator for the controlled sequence. Example 复制 // std_tr1__array__array_reverse_iterator.cpp // compile with: /EHsc #include <array> #include <iostream> typedef std::array<int, 4> Myarray; int main() { Myarray c0 = {0...

To reverse a string by swapping, you can follow the below steps. Start. Take string in variablestr. Take character arrayrevwith size ofstr. This will hold the reversed string. Initialize variableindexwith0. Check ifindexis less than the length ofstr. If false, go tostep 8. ...
Edit & run on cpp.sh Still the program did not print the elements in the reverse array. I am really confused about this. Mar 10, 2011 at 1:23am closed account (D80DSL3A) Line 23 is a bad idea. It copies over num[0] with an uninitialized value. Line 24 is going in the right...
