Files as Parameters and Character Data Retrieve program Grades. cpp and the data file graderoll. dat from the Lab 11 folder. The code is as follows: // FILL IN DIRECTIVE FOR FILES #include #include using namespace std; // This program reads records from a file. The file contains the following: student’s name, //two test grades and final exam grade. It then prints this information to the screen. const int NAMESIZE = 15; const int MAXRECORDS = 50; struct Grades // declares a structure to store information from file { char name[NAMESIZE + 1]; int test1; int test2; int final; }; typedef Grades gradeType[MAXRECORDS]; // This makes gradeType a data type that holds MAXRECORDS // Fill in the code for the prototype of the function readit // where the first argument is an input file, the second is the // array of records, and the third will hold the number of // records currently in the array. int main() { ifstream indata; indata. open("graderoll. dat"); int numRecord; // number of records to read in gradeType studentRecord; if(!indata) { cout << "Error opening file. \n"; cout << "It may not exist where indicated" << endl; return 1; } // fill in the code to call the function ReadIt. // output the information for (int count = 0; count < numRecord; count++) { cout << studentRecord[count].name << setw(10) << studentRecord[count].test1<< setw(10) << studentRecord[count].test2; cout << setw(10) << studentRecord[count].final << endl; } return 0; } // //This procedure reads records into an array of records from an input file and //keeps track of the total number of records //Declare inData: data file containing information to be placed in the array Page 63 of 80 //Declare dataout: an array of records and the number of records // void readIt (// FILL IN THE CODE FOR THE FORMAL PARAMETERS AND THEIR // DATA TYPES.
