Sir why it is showing sum=0

#1

and how to get the correct sum

#2

@rakesh800650
Can you post your code?

#3
#4

@rakesh800650
while(n>0)
{
n=n/10;
k++;
}cout<<k;
this first while loop ends when n becomes 0, so now n is 0, so the following loop doesn’t run coz n = 0,
while(n>0)
{
int r=n%10;
sum+=pow(r,k);
n=n/10;
}cout<<sum;

so the solution is that before running the first loop, preserve n in another variable n1
then run second loop on n1 instead of n. sum won’t show 0 then.
