easy
just make pipe redirection
for example
main.cpp
int main()
{
int i = 0;
for (int j = 0; j < 6 ; j++)
{
scanf ( "%d" , &i );
printf ( "input is %d" , i );
}
return 0;
}
and file a.txt

In windows it will create main.exe
so from command-line just write(main.exe and a.txt are in same folder
(assume))
main.exe < a.txt
output
