;compile ```cpp
#include <cmath>
#include <iostream>
int dectobinary(int n) {
int binary = 0;
int i = 0;
while (n > 0) {
int bit = n % 2;
binary = bit * std::pow(10, i++) + binary;
n = n / 2;
}
return binary;
}
int main() {
std::cout << dectobinary(5);
}

appears to work idk
ruby knoll
;compile
#include <cmath>
#include <iostream>
int dectobinary(int n) {
int binary = 0;
int i = 0;
while (n > 0) {
int bit = n % 2;
binary = bit * std::pow(10, i++) + binary;
n = n / 2;
}
return binary;
}
int main() {
std::cout << dectobinary(500);
}
Yeah seems to work
lusty abyss
.
;compile ```cpp
#include <iostream>
int dectobin(int num) {
int result;
int power = 1;
while (num) {
result += num % 2 * power;
power *= 10;
num /= 2;
}
return result;
}
int main() {
std::cout << dectobin(5);
}
``` small improvement to not use std::pow

lusty abyss
is this your current code?
wild relic
yup
lusty abyss
;compile ```cpp
#include <iostream>
int dectobin(int num) {
int result;
...
mm try this
i want to see wht happens
ruby knoll
;compile ```cpp
#include <iostream>
int dectobin(int num) {
int result;
...
you telling me std pow is slow?
wild relic
lusty abyss
you telling me std pow is slow?
kinda
wild relic
whats wrong with vs code
wild relic
wild relic
yup
lusty abyss
absolutely no idea then
wild relic
ok
wild relic
yes
ruby knoll
Where did you get g++
wild relic
it was working fine yesterday .....just incurred the problem today..... so I thought some problem with code
ruby knoll
My best guess is that you have 2 versions of the code
and the one you're compiling is an old version
ruby knoll
open the contents of the cpp file with notepad
and paste them here
with a codeblock
wild relic
Meaning?
ruby knoll
open the dec_to_binary.cpp file
using notepad
Ctrl A
Ctrl C
then
```cpp
Ctrl V here
```
wild relic
open the dec_to_binary.cpp file
#include<iostream>
#include<cmath>
using namespace std ;
int dectobinary ( int n ) {
int binary = 0 ;
int i = 0 ;
while ( n > 0 ) {
int bit = n % 2 ;
binary = bit*pow(10,i++) + binary ;
n = n / 2 ;
}
return binary ;
}
int main () {
int num ;
cin >> num ;
int binary = dectobinary(num) ;
cout << binary << endl ;
}
did you install any new stuff since yesterday?
wild relic
I don't think so
wild relic
did you install any new stuff since yesterday?
Should I again install the compiler

This version doesn't require exponents.
int dectobinary(int n) {
int binary=0;
int multiplier = 1;
while (n > 0){
if (n & 1){
binary += multiplier;
}
n = n >> 1;
multiplier *= 10;
}
return binary ;
}
i doubt a conditional within a loop is the best
wild relic
!solved
