(adsbygoogle = window.adsbygoogle || []).push({}); 1. Show the evolution/reduction of the system of a 128x128 matrix with a random seed of (1.0) and

with the filling probability of 0.8. Save as a square matrix in a text file(*.txt) that has tab delimited

columns and uses newline as row terminator. Save each iteration as a seperate file with the iteration

number as its filename

3. #include<iostream>

#include<fstream>

#include<time.h>

using namespace std;

int main()

{

srand(1.0);

float P1, P0, P;

int c = 128;

int array [c][c];

for(int i=0;i<c;i++)

{

for(int j=0;j<c;j++)

{

P1 = float((rand()%100)*0.01);

P0 = 0.2;

if (P1>P0)

{

P = 1;

}

else

{

P = 0;

}

array[j] = P;

}

}

ofstream out;

out.open ("try1.txt");

for(int i=0;i<c;i++)

{

for(int j=0;j<c;j++)

{

out<<array[j]<<"\t";

}

out << "\n";

}

system("pause");

return 0;

}

I was able to generate a 128x128 matrix with filling probability 0.8 but I don't know how to show the reduction of the spanning matrix.
