Now, let’s dive into an example demonstrating how to read a file line by line usingifstreamwithgetline()in C++: #include<fstream>#include<iostream>#include<string>intmain(){std::ifstreamfile("input.txt");if(!file.is_open()){std::cerr<<"Error: Unable to open the file."<<std::endl...
In simpler terms,std::ifstreamopens the door to the file, andstd::getlinefetches lines from it. Together, they create a smooth process of turning a file into a neat string. Let’s take a look at the sample code below: example.txt: ...
