Ok, ni gan postingan saya yang terakhir di bulan Desember ini dan di tahun 2012 ini. Kali ini saya akan berbagi lagi program yang saya buat, yaitu program penyelesaian Sistem Persamaan Linier (SPL) dengan metode Gauss Jordan dalam bahasa C++. Nah langsung aja ni codingnya :
#include <iostream.h>
#include <stdio.h>
#include <conio.h>
#include <iomanip.h>
#include <stdlib.h>
main()
{
float matriks[3][4];
float a, b, c, d, e, f, g, h, i, j, k, l;
int x, y;
char lagi;
atas:
clrscr();
cout<<" Program Penyelesaian Matriks 3x3 dengan Metode Gauss Jordan\n";
cout<<" ===============================================================\n\n";
cout<<"\t\t| A11 A12 A13 || x | | p |\n";

cout<<"\t\t| || | | |\n";
cout<<"\t\t| A31 A32 A33 || z | | r |\n";
cout<<endl<<endl;
for (x=0; x<3; x++)
{
for (y=0; y<4; y++)
{

Buat agan-agan yang tidak punya aplikasi untuk menjalankan program C++ jangan khawatir, program gauss jordan.exe bisa agan-agan langsung download di sini. Sekian dulu untuk postingan kali ini, semoga bermanfaat dan dapat membantu. Thanks buat kunjungannya, dan jangan lupa jempol serta kritik dan sarannya tulis aja di komentar :)
Sampai ketemu tahun depan :D
kak boleh minta link barunya ndak ?
