Online judge- input&output

#1

my code:-

#include
using namespace std;
int main(){
cout<<"enter no. of inputs ";
int n;
cin>>n;
while(n>0){
int k;
cout<<"enter the no. : ";
cin>>k;
cout<<"square of “<<k<<” is "<<k*k<<endl;
n–;
}
}

my doubt :

I am not able to link the input .txt file
it throws an error.

error message :

PS C:\Users\USER\Documents> .\s6.exe < input6.txt
At line:1 char:10

  • .\s6.exe < input6.txt
  •      ~

Hello @prateek_5

To run the command s6.exe < input6.txt use cmd and NOT powershell.

#3

I didn’t understand.

what’s the difference between these two?
I am actually new to programming.

(I am using sublime text for windows.)

#4

Hello @prateek_5

Hold windows button on the keyboard and press R
type cmd
Hit enter
cmd will open

Now go to the location where both the code and desktop files are saved using the cd command
Now run s6.exe < input6.txt
it wiil run.

Difference
They are both command line interfaces but powershell is more powerful.
