Write a C program that reads in a list of first and last nam

Write a C++ program that reads in a list of first and last names from an input data file named people.txt. The program should create a user name for each person consisting of the last name and the first initial of the first name. The program should print the first name, the last name, and the created user name for each person to the output data file usernames.txt. The program must use an end-of-file (EOF) loop.

Solution

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

//creating and Opening the output file
dataOut.open(\"D:\\\\usernames.txt\");

//This loop continues to execute until the end of the file
while (!dataIn.eof( ))
{
   
    //reading the firstname and lastname from people.txt file
    dataIn>>fname>>lname;
   
    //Concatinating the firstname first letter with the lastname
    uname=lname+fname.at(index);
   
    //Storing the user name in the txt file
    dataOut<<fname<<\" \"<<lname<<\" \"<<uname<<endl;
}

//Closing the input stream
   dataIn.close()   ;
     
   //Closing the output stream
   dataOut.close();
     
   return 0;
}
