Solution

PROGRAM CODE:

#include <iostream>
#include <string>
#include <iomanip>
#include <fstream>
#include <sstream>

using namespace std;

void display(string array[][3], int lengthofArray) // function to display based on alignment
{
   for(int i=0; i<lengthofArray; i++)
   {
       string name = array[i][0] + \" \" + array[i][1];
      
       for(int j=0; j<20-name.length(); j++) // printing spaces first
       {
       cout<<\" \";
       }
       cout<<name; //printing name (first name and last name)
       double amount = stod(array[i][2]);
       for(int j=0; j<10-array[i][2].length(); j++)
       {
       cout<<\" \";
       }
       cout << fixed << setprecision(2); // setting precision to print the decimal values
       cout<<amount;
       cout<<endl;
   }
}

int main() {
   string array[10][3];
   ifstream infile(\"names.txt\");
   string line;
   int m=0;
   while (getline(infile, line))
{
   istringstream iss(line);
   if (!(iss >> array[m][0] >> array[m][1] >>array[m][2]))
   {
       break;
   }
m++;
}
   display(array, m);
   return 0;
}
