Contoh Program Matrix 4x4 C++

Hai Sobat Blogger !! :)

Kalau sebelumnya saya mengshare contoh program Matrix 3x3, kali ini saya akan mengshare contoh program Matrix 4x4 :)

Disini saya menggunakan aplikasi CodeBlock.

Bagi yang belum punya aplikasinya bisa download disini

ini screanshot nya bisa dilihat dibawah + kode programnya :)

 

 

Program:

#include<iostream>

#include<iomanip>

using namespace std;

float det3(float a, float b, float c, float d, float e, float f, float g, float h, float i)

{

    float n=a*e*i+b*f*g+c*d*h;

    float m=g*e*c+d*b*i+a*h*f;

    cout<<a<<b<<c<<endl;

    cout<<d<<e<<f<<"\t "<<n-m<<endl;

    cout<<g<<h<<i<<endl<<endl;

    return n-m;

}

int main()

{

    int i, j;

    cout<<"---------- Program Matriks 4x4 ----------\n\n";

    cout<<"Masukkan Matriks\n";

    for(i=0;i<4;i++){

        for(j=0;j<4;j++){

        cout<<"["<<i<<"]"<<"["<<j<<"]= ";

        cin>>a[i][j];

        }

    }
