Then, copy c++ code below to a file called read-characters.cpp:Ĭout << "NUMBER OF LINES: " << number_of_lines << endl.

First, create a file called my-input-file.txt which will contain some text.

Every iteration will also print single character including \n to an output.

The code will check for \n, the “new line character” and increase the number of lines stored in the number_of_lines integer variable. C++ code to read characters from a fileĬheck out the C++ code below. Now that we have a compiler installed, move on to the section below to create the program. To install G++ on Arch Linux and Manjaro: To install G++ on CentOS, Fedora, AlmaLinux, and Red Hat: To install G++ on Ubuntu, Debian, and Linux Mint: Otherwise, use one of the following commands below to install the GNU C++ compiler with your Linux distribution’s package manager. If you already have a different C++ compiler installed that you would prefer to use, that will work as well. The file extensions that can be compiled with G++ are.
