Write a program to reverse a string (i) using another array, (ii) without another array.

#include<iostream.h>

#include<conio.h>

#include<stdio.h>
#include<string.h>

void main()
{

int str[50], rev[50];

cout<< "\n Enter a string :";
 gets(str);
int l = strlen(str);

/* Reverse String using another array */
for( int i = l-1, k = 0 ; i>= 0 ; i--, k++)
rev[k] = str[i];

 rev[k] = '\0';

cout<< "\n Original String is "<< str;
cout<< "\n Reverse String is "<< rev ;
cout<< "\n Reverse String is ";

/* Reverse String without using another array */
for(  i = l-1 ; i>=0 ; i--)
 cout<< str[i];

 getch();

}
