C++ code for reading unknown size matrix from text file
In this post, I upload my program {C++ code for reading unknown size matrix from text file } <download> which imports an arbitrary size matrix (or 2D array) from text (txt) file. This is c++ code.
The below is an execution result. The first figure is a text file including a matrix, the next figure is an execution screen. It’s very easy to use.
text file to import. It has an arbitrary size matrix
execution screen image, it imported the matrix from the above text fileSometimes, we want to import a matrix that we don’t know its size, especially when the file was generated from other programs.
I had googled for long time, and I realized that it is not easy to find. So, I made.
You don’t need to indicate the size of matrix, (cols and rows). It automatically imports and outputs, double type vector, column and row size. It is very easy to use, and you can download the source code from here <download>.
The only thing you should do is just download the source code, and import “x.txt” or “y.txt” which includes an arbitrary matrix.
Enjoy my program { C++ code for reading unknown size matrix from text file } Then good luck.
