Write a fragment of code that reads in strings from standard input, until end-of-file and prints to standard output the largest value. You may assume there is at least one value. (cascading/streaming logic, basic string processing)

Sample input file: numbers. txt

8 9 7 67 78 45 67 99 1001

Sample Output:

The largest value is:1001

Code to Copy:

/ / include stdafx, if using visual studio.

#include "stdafx. h"

/ / declare the necessary header files.

#include

#include

#include

using namespace std;

/ / Start the main function

int main ()

{

/ / create the object of ifstream.

ifstream in_file;

/ / Open the file

in_file. open ("numbers. txt");

/ / Declare the string variable

string str;

/ / Declare the integer variables.

int maximum = 0;

int num;

/ / Check whether the file open

if (in_file. is_open ())

{

/ / Traverse the file till the end.

while (! in_file. eof ())

{

/ / traversing the value.

in_file >> str;

/ / convert the string into integer.

num = stoi (str);

/ / Check whether value is max or not.

if (maximum < num)

{

/ / Update the value of maximum.

maximum = num;

}

}

}

/ / Display the statement on console.

cout << "The largest value is:" << maximum << endl;

/ / Close the file.

in_file. close ();

system ("pause");

return 0;

}
