Hello, i'm a really beginner in c++ code and i have a problem regarding the possibility to read a text file, display the values saved on the file directly on the command prompt line and make simply operation on that data. As example, compute the mean value. The text file is made of a 3 column of data.
how it is possible to make a graph with this value? as example taking the first column as x axis and the second column as y axis.
