Thread: encripting 4-digit integer?

Code:

#include<iostream>
#include<conio.h>

using std::cout;
using std::cin;
using std::endl;

int main()
{
    // declare variables
    
    int num,digit1,digit2,digit3,digit4,sum1,sum2,sum3,sum4;
    
    // initialize variables
    
    sum1=0,sum2=0,sum3=0,sum4=0;
    
    cout<<"\nEnter a 4 digit integer:\t";
    cin>>num;
    
    // separate the integers
    
    digit1=num%10;
    
    num/=10;
    digit2=num%10;
    
    num/=10;
    digit3=num%10;
    
    num/=10;
    digit4=num%10;
    
    // replace digits
    
    sum1=(digit1+7)%10;
    sum2=(digit2+7)%10;
    sum3=(digit3+7)%10;
    sum4=(digit4+7)%10; 

    // swap digits
    
    cout<<"Encripted integer\t\t";
    
    cout<<sum2<<sum1<<sum4<<sum3;
    
getch();
}

Is this correct encription?I was trying to swap the first digit with the third one and second with the fourth one, ofcourse after replacing each digit with its sum plus 7 % 10.

Code:

#include<iostream>
#include<conio.h>

using std::cout;
using std::cin;
using std::endl;

int main()
{
    // declare variables
    
    int num,digit1,digit2,digit3,digit4,dcript1,dcript2,dcript3,dcript4;
    
    // initialize variables
    
    dcript1=0,dcript2=0,dcript3=0,dcript4=0;
    
    // read integer
    
    cout<<"\nEnter the integer to be decripted:\t";
    cin>>num;
    
    // separate integers
    
    digit1=num%10;
    num/=10;
    digit2=num%10;
    num/=10;
    digit3=num%10;
    num/=10;
    digit4=num%10;
    num/=10;
    
    // print decripted digit
    
    if((digit1<7||digit2<7)||(digit3<7||digit4<7))
    {
        dcript1=(10+digit1)-7;
        dcript2=(10+digit2)-7;
        dcript3=(10+digit3)-7;
        dcript4=(10+digit4)-7;
        
        cout<<"\nDecripted 4-digit integer:\t\t";
        cout<<dcript2<<dcript1<<dcript4<<dcript3;
    }
    else
        dcript1=(digit1-7)%10;
        dcript2=(digit2-7)%10;
        dcript3=(digit3-7)%10;
        dcript4=(digit4-7)%10;
           
getch();
}

See the attachment , the only prob is it outputs last integer thrice.

sorry couldn't attach the file

Honestly dude XMAS?? There no rest for the wicked??
