SY_BCS_CPP_Slip no:10_1,13_1,23_2

 Slip no : 10_1,13_1,23_2

Implement a class "invertdata" to overload "invert" function as follows:

a) int invert ( int) - returns the inverted integer. Eg. invert(5438) will return 8345             [10]

b) char * invert ( char *) – returns the reversed string – reverse(“comp”) will return ”pmoc”[8]

c) void invert( int * ) – will reverse the array order – An array [5, 7, 12, 4] will be inverted to [4, 12, 7,5].                                                                                                                                   [7]

Write a main function that uses the above class and its member functions.                        [5]

#include<iostream>

#include<string.h>

using namespace std;

int cnt=0;

class invertdata

{

            public:

            int invert(int n)

            {

                        int rev=0,r;

                        while(n!=0)

                        {

                        r=n%10;

                        rev=rev*10+r;

                        n=n/10;

                        }

            return rev;

            }

            char *invert(char *s1)

            {

                        int i,j,len;

                        len=strlen(s1);

                        char *s2=new char[len+1];

                         

                        for(i=(len-1),j=0;i>=0;i--,j++)

                        {

                                    s2[j]=s1[i];

                        }

                        s2[j]='\0';

                        return s2;

            }

            void invert(int *p)

            {           int i;

                        for(i=cnt-1;i>=0;i--)

                        {

                                    cout<<p[i]<<"\t";

                        }

            }
