I need to know what is wrong in my code
#include
#include
using namespace std;
int btod(int n){
int s=0;
int b;
for(int i=0;i<=n;i++){
int p=n%10;
b=pow(2,i);
s=s+p*b;
n=n/10;
}
return s;
}
int main(){
int n;
cin>>n;
int w=btod(n);
cout<<w<<endl;
}

Sir, Why can’t we use for loop in this code as I wrote it earlier.

basically what u were doing was running a loop for n times… but we just need to run a loop till n is not zero…

#5

i hope its clear now?
