How do you reverse a string in C++ using Strrev?

strrev() is a pre-defined function in C++, defined inside the cstring. h header file. It is extensively applicable for reversing any C-string(character array). Further, it only requires the base address of the string as its argument and reverses the string accordingly.

What is reverse function?

The REVERSE function accepts a character expression as its argument, and returns a string of the same length, but with the ordinal positions of every logical character reversed. … The REVERSE function returns a string of the same data type as its source_string argument.

How do you reverse a string in a list Python?

In Python, you can reverse the items of lists ( list ) with using reverse() , reversed() , and slicing. If you want to reverse strings ( str ) and tuples ( tuple ), use reversed() or slice.

Is Python a palindrome?

Explanation: In the above program, first take input from the user (using input OR raw_input() method) to check for palindrome. Then using slice operation [start:end:step], check whether the string is reversed or not. Here, step value of -1 reverses a string. If yes, it prints a palindrome else, not a palindrome.

How do you reverse a loop in Python?

But Python does have a built-in reversed function. If you wrap range() inside reversed() , then you can print the integers in reverse order. range() makes it possible to iterate over a decrementing sequence of numbers, whereas reversed() is generally used to loop over a sequence in reverse order.
