Question

Modify PartTwo.cpp so that it is uses a vector, named vect, instead of an array.

PartTwo.cpp Is posted here:

// This program reads data from a file into an array. Then, it
// asks the user for a number. It then compares the user number to
// each element in the array, displays the array element if it is larger.
// After looking at entire array, it displays the number of elements in the array larger
// than the user number.

{
   int stepsTaken[ARRAY_SIZE];    // Array with 365 elements
   int count = 0;    // Loop counter variable

   ifstream inputFile;     // Input file stream object
  
   // Open the file.

   // Read the numbers from the file into the array.
   while (count < ARRAY_SIZE && inputFile >> stepsTaken[count])
        count++;
  
   // Close the file.
   inputFile.close();

   // Prompt user for a number

Output:

Please enter an integer between 1000 and 12000: 5514 The numbers greater are: 58962 There are 1 number (3) greater than your number 5514 Your number 5514 is in the array.

Hope it will be usefull and do comments for any extra info if needed. Thankyou
