digit reverse in C
 
All my greetings to everyone.
With a lot of respect to all members of this forum ,please i'm struggling since already many days to solve this problem.In fact how can we reverse a number (e.g 12345 to 54321)using only looping without array nor pointer or other advanced codes.Also for a number like 1000 it must be 1 inspites of 0001.
thank you for your support Assalam :thinking: :thinking:

Here i am just giving you an idea. Solve it by making it efficient and accurate.

Code:
int nDigit=1,result=0;
while(n>0)
{
  n=n/10;
  ++nDigit;
}
for(int i=0; i<nDigit;++i)
{
  result = result+ n%10 +pow(10 , nDigit-i);
  n = n/10;
}
