hello @tanvi2002 this is the concept for the understanding how online compilers when you submit any code works there.
they have a file there for the inputs from which they give input to your code and they have one output file from which they compare your output .
if you are using sublime for your coding part then for the execution you always have to go to the terminal to run your code .
but if you type these lines in your main function :
#include <bits/stdc++.h>

using namespace std;

int main() {

#ifndef ONLINE_JUDGE

freopen("input.txt","r",stdin);

freopen("output.txt","w",stdout);

#endif

cout<<"Hello World!";

return 0;

}
then you will see that there will be output in your output.txt file . and your program will take input from your input .txt file .
i hope i have cleared your doubt .
Happy Learning !!
