just iterate over them

string ans="";
while(num>0){
     ans=('0'+num%10)+ans;
     num=num/10;
}

I don’t think there is any other direct way :slight_smile:

but this will give reverse order right

#6

No it should give correct order because I am appending ans later here

Here try this in ide

#include <iostream>
using namespace std;
int main() {
    int num=1234;
    string ans="";
    while(num>0){
        ans=(char)('0'+num%10)+ans;
        num=num/10;
    }
    cout<<ans<<endl;
}
