This what really happens when you run a program on codechef:

  1. It reads the input from an input text file.

  2. It writes the output to another text file. The output statements in your program put some content on the console, here these output statements put this output in the output text file.

For example,

t=3;

for(i=0;i < t;i++)

{cin >> n;

cout << i << endl;

}

On console if you take input as n=100 for all n. This would have looked like:

100

0

100

1

100

2

OUTPUT FILE:
0

1

Now consider the code:

t=3

for(i=0;i < 3;i++)

cin>>n;

for(i=0;i < 3;i++)

cout << i << endl;

On console if you take input as n=100 for all n. This would have looked like:

100

100

100

0

1

2

OUTPUT FILE:

0

1

So you can clearly see that contents of the output file are the same in both the cases.
After generating these output files they are simply checked against the output correct files that are created by the problem setter.
