Below is a program to reverse a string using pointer:#include <stdio.h> int main() { printf("\n\n\t\tStudytonight - Best place to learn\n\n\n"); char str[100]; char rev[100]; char *sptr = str; // sptr stores the base address of the str char *rptr = rev; // rptr ...
Approach 2 – Using spread operator const ReverseString = str => [...str].reverse().join(''); ReverseString("codedamn") //Output- nmadedocCode language: JavaScript (javascript) Here the spread operator is used to convert string to an array of characters(codedamn={c,o,d,e,d,a,m,...
The source code to reverse a string using recursion is given below. The given program is compiled and executed using GCC compile on UBUNTU 18.04 OS successfully. // C program to reverse a string using recursion#include <string.h>#include <stdio.h>voidStrRev(charstr[],inti,intlen) {chart;...

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...
Then in the project, we will develop a recursion function which we will call later on in the code for reversing the strings. Declare a function with the return type “void” and name it “reverse.” The parameters of this function will be char type pointer string as “char*string.” In...

A simple function that prints out a word that starts from the current character pointer. We loop and print till we get a end-of-string ('\0') or a blank: #include<iostream>voidprint_word(constchar* x){while(*x !=' '&& *x !='\0'){ ...
