help me in this program....

Write a program that prompt the user ti input an integer and then outputs the
numbers with digits reversed. for example, if the input is 12345 the output should be 54321. Your program should find the summation of all digits, for previous example the summation will be 15.

this is my solution.. but. I think.. its not correct..

[CODE=cpp]
#include <iostream>
#include<fstrea m>
using namespace std;

int main()
{

int num,digit,sum=0 ;

ifstream infile;
ofstream outfile;

infile.open("in Data.txt");
outfile.open("o utData.txt");

infile>>num;
outfile<<"Numbe r: "<<num<<end l;



while (num>0)
{
digit=num%10;
num=num/10;

if(digit>0)
num=num%10;
num=num/10;
sum++;

}
outfile<<"Numbe r in reverse Order:"<<num<<e ndl;

outfile<<"Summa tion of Digits: "<<sum<<end l;



infile.close();
outfile.close() ;

return 0;
}
[/CODE]

can any body help me???

Your code compiles and runs without errors, are you getting a logical error? Can you describe your issue, show us output?

Also, next time, please read and follow this .

What is going on here?
[CODE=cpp]

while (num>0)
{
digit=num%10;
num=num/10;

if(digit>0)
num=num%10;
num=num/10;
sum++;

}[/code]

Your sum variable is just incrementing, it's not getting the values you're pulling added to it.

Also, you're just dividing the numbers by 10, not reversing the order... Can you come up with an algorithm for that?

[CODE=cpp]
while (num>0)
{
digit=num%10;
num=num/10;

if(digit>0)
num=num%10;
num=num/10;
sum++;

}
[/code]

Bad indentation screams for errors like these. You can easily follow what is
happening here in this loop (hint: pencil and paper!). That if statement doesn't
make any sense.

kind regards,

Jos

ps. and please correct your indentation.

when I input this:

inData.txt:
12345

I get this:

outData.txt:
Number: 12345
Number in reverse Order:0
Summation of Digits: 1

But , the outData should be like this:

outData.txt:
Number: 12345
Number in reverse Order:54321
Summation of Digits: 15

How about something like...

Thanks all..

and; if any one have another indentation for this, I will be grateful.

Thanks again..
