C++ Programme for a function to encode a string that is passed to it. The string should get converted into an unrecognizable form.

#include<iostream.h>

#include<conio.h>

#include<string.h>

#include<stdio.h>

void encode(char str1[],int l);

int main()

{

               char str[30];

               cout<<"Enter an string:";

               gets(str);

               int len=strlen(str);

               encode(str,len);

               return 0;

}

void encode(char str1[],int l)

{

               int i;

               for(i=0;i<l;i++){

                              str1[i]=str1[i]+10;

               }

               cout<<"\nThe encoded string is:"<<endl;

               for(i=0;i<l;i++){

                              cout<<str1[i];

               }

               cout<<"\nThe proper string is:"<<endl;

               for(i=0;i<l;i++)

                              str1[i]=str1[i]-10;

               for(i=0;i<l;i++)

                              cout<<str1[i];

}

OUTPUT:

 Enter an string:KARTHIK
