Why this code go wrong when i put s=0; in the initial conditions and give a true response when i put this condition after n=i;

#include <iostream> using namespace std; int main() { int a,s=0,i,n; for (i=11;i<=99;i++) { n=i; cout<<i<<":"; while (n!=0) { a=n%10; s=s*10+a; n=n/10; } cout<<s<<endl; } return 0; }

Nariman Tajari this change in behaviour is due to the value updated in 's' each time the value of 'n' changes. You must make the variable 's' equal to 0 each time after your while loop is completed. If you do not make s=0 inside the for loop then it will always print the updated value of 's' which will keep on increasing after each iteration.
