C++ help

How do you make a while loop that can go to different students and print out all the students classes, class credit, grades then calculate the gpa of the classes?

This is the code I currently have below:

#include #include // needed for outFile/ inFile #include // needed for getline #include // printing needed decimal

using namespace std;

int main() {

// Creating the grades.dat file below

string dataname = "grades.dat"; // create the name of the file ofstream outFile; outFile.open(dataname.c_str());

if (outFile.fail()) { // print out a fail

cout

//Student files below to be implemented into the .dat file outFile

//Print success of the student files above cout

// Created the grades.dat file above

//Creating the console print out below

double x = 0; // used to calculate GPA int sum = 0; // passing classes counted int value; // number for each letter grade double gpa = 0; // calculate gpa

/avigating the grades.dat file below string StudentID[10]; string Studentname[10]; string Studentclass[10]; string Studentcredit[10]; string Studentgrade[10];

ifstream inFile; inFile.open(dataname.c_str()); /avigating the grades.dat file above

if (inFile.fail()) { // print out a fail

cout

//collecting data after navigating the .dat file getline(inFile, StudentID[0]); getline(inFile, Studentname[0]);

cout

cout

while (StudentID[0] == 1){

for (int i = 0; i

if (i != 0) {

getline(inFile, StudentID[i]); getline(inFile, Studentname[i]); getline(inFile, Studentclass[i]); getline(inFile, Studentcredit[i]); getline(inFile, Studentgrade[i]);

} else {

getline(inFile, Studentclass[i]); getline(inFile, Studentcredit[i]); getline(inFile, Studentgrade[i]);

}

// grading system below if (Studentgrade[i] == "A") {

value = 4; sum = sum + 1;

} else if (Studentgrade[i] == "B") {

value = 3; sum = sum + 1;

} else if (Studentgrade[i] == "C") {

value = 2; sum = sum + 1;

} else if (Studentgrade[i] == "D") {

value = 1; sum = sum + 0;

} else {

value = 0; sum = sum + 0;

}

// calculating the values and where the class are "eligible" for passing string str = Studentcredit[i]; x = x + value;

cout

}

gpa = (x / sum); } return 0; }

The output should look something like this:
