C++ array/matrix in a file -

completely new c++ , have use programming language. , never done programming before.

basically need read matrix stored file it's output can seen when press debug button.

when i've tried doing matrix

1 3 5  2 4 6  5 7 9 

when come reading it, comes matrix in line so.... 1 3 5 2 4 6 5 7 9.

so know how it's read matrix, if that's possible?

in future need find determinant of matrix e.t.c. , other sums between multiple matrices.

here have:

#include <iostream> #include <conio.h> #include <cmath> #include <fstream> #include <cstdlib>  using namespace std;   int main() {     char filename[50];     ifstream matrixa;     cin.getline(filename, 50);     matrixa.open(filename);      if (!matrixa. is_open())     {         exit (exit_failure);     }     char word[50];     matrixa >> word;     while (matrixa.good())     {         cout << word << " ";         matrixa >> word;     }     system("pause");     return 0; } 

if have array of 9 numbers, can read them in ifstream object

float elements[9];  ifstream reader(/*your file*/);  reader >> elements[0] >> elements[1] >> elements[2]; //read first line reader >> elements[3] >> elements[4] >> elements[5]; //read second line reader >> elements[6] >> elements[7] >> elements[8]; //read third line  reader.close(); 

better still can create class / structure matrix , read in using member function, , add operators (such determinant).

edit:

if want print matrix in... matrix form, use std::getline;

ifstream reader(/*your file*/);  char buffer[300];  //1st line std::getline(reader, buffer); cout << buffer << endl;  //2nd line std::getline(reader, buffer); cout << buffer << endl;  //3nd line std::getline(reader, buffer); cout << buffer << endl;  reader.close(); 

this assume format data matrix.
