Object Oriented Programming - Old Questions

4. Write a member function called reverseit() that reverses a string ( an array of character). Use a for loop that swaps the first and last characters, then the second and next-to last characters and so on. The string should be passed to reverseit() as an argument.

#include<iostream.h>

#include<conio.h>

#include<stdio.h>

#include<string.h>

void reverseit(char *p)

{

    int j;

    int len=strlen(p);

    j=len-1;

    for(int i=0;i<len/2;i++)

    {

      char a=p[i];

      p[i]=p[j];

      p[j]=a;

      j--;

    }

    cout<<"\\n\\nReverse Of String :";

    puts(p);

}

void main()

{

    char str[50];

    char ch;

    cout<<"\\nEnter The String : ";

    gets(str);

    reverseit(str);

    getch();

}
