CS-415 Assignment 1 (Fortran) Iyengar Spring 2025

Write a Fortran program to solve a set of 3 simultaneous equations. An input file SIMEQ.DAT contains a set if simultaneous equations described as follows:

Example:

8 9 5 14

-3 -2 2 10

1 4 -5 -35

Describes 3 simultaneous equations with 3 variables, like

8x + 9y + 5z = 14; -3x – 2y + 2z = 10; and 1 x + 4 y – 5 z = -35;

Solve these equations by Gaussian elimination and output the solution.

Output should look like

X = 2

Y = -3

Z = 5

Install a Fortran development environment and use to develop your application. To get started – develop steps to solve this with just if-then-else and loops and basic reads. Then translate those steps into Fortran.

Save your source code to your folder by midnight 3/2/2025.
