Learn how to use getline() function and many string member functions to process input file one line at a time and display data in groups.
Read ship records from the input file shipRecords.txt
1 \"Royal Queen\" 2015 160
2 \"Carnival\" 2016 1600
1 \"Ocean King\" 2013 110

Solution
Dear Student,
Here is the partial program please wait for some time i am sorting out the issue and will soon update the program,,,,
-------------------------------------------------------------------------------------------------------------------------------------
program...
#include<iostream>
#include<iomanip>
#include<string>
#include<stdlib.h>
#include<fstream>
using namespace std;
int main()
{
int ship_type[10];
string line;
char fname[20];
char lname[20];
int year[10];
int capacity[10];
int Cap =0;
int i =0;
int count = 0;
int c =0;
ifstream infile;
infile.open(\"shipRecords.txt\");
if(!infile)
{
cout<<\"File does not exist\"<<endl;
return 1;
}
//while(!infile.eof())
while(getline(infile, line))
{
infile>>ship_type[i]>>fname[i]>>lname[i]>>year[i]>>capacity[i];
i++;
count++;
}
for(i=0;i<count;i++)
{
if(ship_type[i]==1)
{
c++;
//Cap = Cap + capacity[i];
cout<<setw(20)<<left<<fname[i]<<\" \"<<lname[i]<<setw(20)<<left<<year[i]<<setw(20)<<left<<capacity[i]<<endl;
cout<<setw(60)<<c<<\"Cargo Ships\"<<endl;
//cout<<setw(60)<\"Total Cargo Capability \"<<Cap<<endl;
}
if(ship_type[i]==2)
{
c++;
//Cap = Cap + capacity[i];
cout<<setw(20)<<left<<fname[i]<<\" \"<<lname[i]<<setw(20)<<left<<year[i]<<setw(20)<<left<<capacity[i]<<endl;
cout<<setw(60)<<count<<\"Cruise Ships\"<<endl;
//cout<<setw(60)<\"Total# of Passengers\"<<Cap<<endl;
}
}
//cout<<ship_type<<fname<<lname<<year<<capacity<<endl;
infile.close();
return 0;
}
