Implement a functionvoid reverse(char* str)in C or C++ which reverses a null-terminated string. This is (implicitly) asking for an in-place reversal of the string. We start by finding the end of the string (or equivalently, its length). Then we swap the last character and the first ch...
saving you a byte of memory... For another 4 bytes, find the end of the string yourself using a single pointer instead of using strlen which needs a 4-byte integer. Now you're down to two char*'s ... I would be surprised if there is a solution that uses less than that ... se...

2. Reverse Words in a String Given an input string, reverse the string word by word. Example: the skyisblue blueissky the Note: A word is defined as a sequence of non-space characters. Input string may contain leading or trailing spaces. However, your reversed string should not contain ...

Write a C++ program that reverses a string using recursion without any library functions. Write a C++ program to reverse a string by swapping its characters in-place using two pointers. Write a C++ program that converts a string to a character array and then reverses it using a for loop. ...
string as “htolc”. There exist several methods to perform the string reversal in the C, and they are strev func (), recursion func (), and string reversal using the pointers. We can also verify the palindrome string using the string reversal methods. A palindrome is a string whose ...
