INPUT FROM FILE

#1

AS PRATEEK BHAIYA SAID,
We can take input from the file by using

.\program.cpp < input.txt

But It is not working in my terminal, it is showing error

#2

correct way to take input from a file is
./a.out < input.txt

here a.out is output file and
input.txt is input file

#3

But as the bhaiya said in the lecture, in that way it is not working?

#4

in which video bhaiya told that??
also specify the time span
i will look into it

#5

Yes in the module "GETTING STARTED WITH C++ " in the lecture “Online-judge input and output” and time span is 4:50 onwards

#6

bhaiya has also use the same syntax

use forward slash(/) not () also bhaiya use output file " handling_multiple_inputs " not use the code file name as you do

your mistakes

  1. use backslash instead of forward salsh
  2. use codefile name program.cpp instead of outputfile name

i hope this helps
if yes hit a like and don’t forgot to mark doubt as resolved
if you have more doubts regarding this feel free to ask

#7

Yes, but handling_multiple_inputs is the name of the cpp file

#8

no it is output file name
cpp file name is handling_multiple_inputs.cpp

#9

ohk, Thanks for your help
