<pre>
    ### I compiled the below code using ```clang++``` and ```g++```.

### Time Taken 
> Clang++: ```1.2 sec```
> G++  : ```.005 sec``` 

```cpp
#include<iostream>

int main ( void ) 
{
    std::ios_base::sync_with_stdio( false );
    std::cout.tie( nullptr );

    for(unsigned int i = 0 ; i < 10000 ; ++i)
    {
         std::cout << i << '\n';
    }
    
    return 0;
}
```

### then I replaced std::cout with printf and then the time taken:
> Clang++: ```0.256 sec```
> G++       : ```0.249 sec```

## 🟡Anyone, please try to optimize std::cout which matches the speed of ```g++```.
