Write a C program that uses Gaussian-Jordan technique to solve simultaneous linear equations. The program should be flexible enough to solve any number of unknowns/linear equations. One should just change row size, column size and the array elements to fit the new dimensions. The rest of the program should work without any changes. What should be submitted : 8C-1: Program to solve 3 linear equations and the output showing the result. 8C-2 : Program to solve 4 linear equations and the output showing the result.

Question

b) Ignore the array's row/ column subscript of 0.
Requirement 8C-2
Next modify the program by changing only the row size, column size and the array elements to solve 4
linear equations with 4 unknowns as shown below.
w + 2x - y +z = 6
-w +x+ 2y - z = 3
2w - x+ 2y + 2z = 14
w + x- y + 2z = 8
Use (hardcode) the following coefficients/matrix within your program to solve above equations. The
expected output is as follows.
Initial matrix
1.000 2.000 -1.000 1.000 | 6.000
-1.000 1.000 2.000 -1.000 | 3.000
2.000 -1.000 2.000 2.000 | 14.000
1.000 1.000 - 1.000 2.000 | 8.000
The solution is:
X1 = 1.000
X2 = 2.000
X3 = 3.000
X4 = 4.000
Note: X1 represents w, X2 represents x, X3 represents y and X4 represents z.

Write a C program that uses Gaussian-Jordan technique to solve simultaneous linear equations.
The program should be flexible enough to solve any number of unknowns/linear equations. One should
just change row size, column size and the array elements to fit the new dimensions. The rest of the
program should work without any changes.
What should be submitted :
8C-1: Program to solve 3 linear equations and the output showing the result.
8C-2 : Program to solve 4 linear equations and the output showing the result.
Requirement 8C-1
Initial program should be setup to solve 3 linear equations with 3 unknowns as shown below.
2x + 4y + 6z = 22
3x + 8y + 5z = 27
-x + y + 2z = 2
Use (hardcode) the following coefficients/matrix within your program to solve above equations. The
expected output is as follows.
Initial matrix
2.000 4.000 6.000 | 22.000
3.000 8.000 5.000 | 27.000
-1.000 1.000 2.000 | 2.000
The solution is:
X1 = 3.000
X2 = 1.000
X3 = 2.000
Note: X1 represents x, X2 represents y, and X3 represents z.
Using Xn to represent the variables makes easier to print out the answer for the flexibility requested
below.
For convenience, you could declare the array one size greater (row +1, column +1) so that you can
a) Use array subscript / index starting at 1 instead of 0. Makes it easier to match the row / column
counter used in the loop and the row/column subscript used with the array.
