C++ Program to Represent Linear Equations in Matrix Form

This is a C++ Program to represent a set of linear equations in matrix form.

Here is source code of the C++ Program to Represent Linear Equations in Matrix Form. The C++ program is successfully compiled and run on a Linux system. The program output is also shown below.

```
#include<iostream>
```
```
#include<conio.h>
```
```
 
```
```
using namespace std;
```
```
 
```
```
int main(void)
```
```
{
```

    char var[] = { 'x', 'y', 'z', 'w' };

    cout << "Enter the number of variables in the equations: ";

```
 
```
```
    int n;
```
```
    cin >> n;
```

    cout << "\nEnter the coefficients of each variable for each equations";

```
    cout << "\nax + by + cz + ... = d";
```
```
    int mat[n][n];
```
```
    int constants[n][1];
```
```
    for (int i = 0; i < n; i++)
```
```
    {
```
```
        for (int j = 0; j < n; j++)
```
```
        {
```
```
            cin >> mat[i][j];
```
```
        }
```
```
        cin >> constants[i][0];
```
```
    }
```
```
 
```

    cout << "Matrix representation is: ";

```
    for (int i = 0; i < n; i++)
```
```
    {
```
```
        for (int j = 0; j < n; j++)
```
```
        {
```
```
            cout << " " << mat[i][j];
```
```
        }
```
```
        cout << "  " << var[i];
```

        cout << "  =  " << constants[i][0];

```
        cout << "\n";
```
```
    }
```
```
    return 0;
```
```
}
```

Output:

$ g++ MatrixRepOfEquations.cpp
$ a.out
 
Enter the number of variables in the equations: 3
 
Enter the coefficients of each variable for each equations
ax + by + cz + ... = d
1 2 3 4
1 2 6 8
2 3 9 8
Matrix representation is:  
 1 2 3  x  =  4
 1 2 6  y  =  8
 2 3 9  z  =  8
