Does the strrev() modify the array into which the s points to? If yes, then the return value (a pointer) of the function has the same value as the input parameter s. If not, then the function must dynamically allocate memory for the C-string that it will return. In any case, the...
The _strrev function reverses the order of the charactersinstring. The terminatingnullcharacter remainsinplace. _wcsrev and _mbsrev are wide-character and multibyte-character versions of _strrev. The arguments andreturnvalue of _wcsrev are wide-character strings; those of _mbsrev are multibyte-cha...
3. Reverse a string by copying string from right to left into a new string 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 ...

To reverse a string "in place" without using a temporary string, use the reverse function template in the <algorithm> header: Demo Code#include <string> #include <iostream> using namespace std; int main() {// w w w . ja v a 2s .co m string s = "this is a test"; cout <<...
LeetCode解题思路:344. Reverse String Write a function that takes a string as input and returns the string reversed. Example: Given s = "hello", return "olleh". 题意:翻转字符串,从头到尾翻转。 基本思路: 1.如果对指针操作还不熟练,可以通过另分配n个字节的内存来进行翻转。即将字符串从后向前读...
