Question

What is a simple translation in code for ‘textscan’ from matlab into C or C++?
I am using Ubuntu and I am trying to translate a Matlab code into C++.
Thank you very much.

First, the answer is not the same if you’re using C or if you’re using C++. These are different programming languages.

Matlab is a much higher-level language than C and C++. In Matlab textscan reads from files or strings. C and C++ have different mechanisms for that.

To read from a file :

In C, you should use the FILE object and its associated functions (fopen, fgets …) from the header file : stdio.h.

In C++, you should use std::ifstream from the <fstream> header file. For formatted input use the >> operator.

To read from a string :

In C, you might want to look at the functions in the string.h header.

In C++, the better way is to use the std::istringstream class from the sstream header file.
