Question

The program needs to:

Read input integers from a file into an array A; there will be up to 50 elements.
Then fill two new arrays with elements selected from A as indicated below.
Array A5 will contain all the elements of A that are multiples of 5.
Array Aodd will contain all the elements of A that are odd integers.
Output the contents of these arrays, with labels, to a file...

How do I fix the program below to have an array containing 50 elements and reading from a file?
Program below :


#include <iostream>
#include <fstream>

using namespace std;

ifstream infile;
ofstream outfile;

int main()
{
infile.open("unknown.txt");
outfile.open("list.txt");

int new_num;
int min;


infile >> new_num;
min = new_num;

while (infile)
{
  if (new_num < min)
   min = new_num;
  infile >> new_num;
}
outfile << "Minimum number is " << min << endl;

infile.close();
outfile.close();

return 0;
}

Explanation / Answer

unknown.txt (Save this fuile under D Drive.Then the path of the file pointing to it is D:\unknown.txt)

________________

list.txt (We can See this file under D Drive.As we specified the path of the output file as D:\list.txt)

Array Elements which are multiplies of 5 are :
45 15 20 25 30 35 40 45 50 55 55
Array Elements Which are odd numbers :
23 45 15 17 19 21 23 25 27 29 31 33 35 37 39 43 45 47 49 51 53 55 55 57
