I'm gonna give you a hint Have a variable as frequency counter for digit <m>, set it to zero. To extract last digit of an integer <N>, we modulo <N> by 10 Example: int N = 12345; int digit = N % 10; // <digit> is 5 Now we want to get all the digits one by one so we repeat the above steps to extract last digit, followed by removing the digit that was already extracted by dividing <N> by 10. Keep doing it while <N> is non zero. For this, we're gonna need to use a loop to repeat the steps int N = 12345; int digit = N % 10; // <digit> is 5 N /= 10; // now <N> is 1234, digit 5 is removed Repeat the steps above to get each digit, and when <digit> equals <m>, increment the frequency counter.

Nevermind i found my error it was when i assigned the if statement i used = instead of ==

#include <bits/stdc++.h> using namespace std; #define ll long long int main() { ll n,m; cin>>n>>m; while(n>0) { if(m==n%10) { cout<<"YES"; return 0; } n/=10; } cout<<"NO"; }

You are currently taking HTML course, why try C++ assignment when you haven't even started learning it? that's suicidal ...

int m, n, counter=0, digit; cin>>n; cin>>m; while(n!=0){ digit=n%2; n/=10; } I Came this far but how do i make the counter count the number of times m was repeated i tried using if statements within the loop but it doesnt work
