Please tell me the mistake in my code

include

using namespace std;

int countdigit(int n){
int j=0;

while(n!=0){
     n = n/10;
   j++;  
}

return j;
}

int arms(int n){
int num = 0;
int i;
while(n!=0){
i = n%10;
num += pow(i , countdigit(n));
n /= 10;
}
return num;
}

void checknum(int n){
int ans = arms(n);

if (n == ans)
{
    cout<<"True";
}
else
{
    cout<<"False";
}

}

int main(){
int n;
cin>>n;
checknum(n);
return 0;

@abhinavssr2003_eab0717682969e5c, to pass test cases use long long and “true” “false” not starting with capital

but why we have to create one bucket temp?? why it is not running with n only??

@abhinavssr2003_eab0717682969e5c,
u have to keep the power equal to count of original no only
