Question
I've having trouble making a username that goes right after the ID column It needs to say the initials of each student and then the ID number of them after it. Example: Bonebrake Nicole 1111 bn1111 90 85 50 78 85 77.60 C
I htink they way I am doing this may be a bit over complicated but everyone else works well I'm just very stuck on the username portion.

Explanation / Answer
There two issues in your code
1) formatting username in readline function
2) Not assigning username to usernameL variable in student structrue and not using this varaible in console output
Student* readIn(int total, string username)
{
ifstream dataIn;
dataIn.open("D://ravi/Cheg//grade.txt");
Student* SL;
SL = new Student[total];
for (int i = 0; i < total; i++)
{
dataIn >> SL[i].lname;
dataIn >> SL[i].fname;
dataIn >> SL[i].Id;
dataIn >> SL[i].testScore[0]
>> SL[i].testScore[1]
>> SL[i].testScore[2]
>> SL[i].testScore[3]
>> SL[i].testScore[4];
SL[i].fullName = SL[i].lname + ", " + SL[i].fname;
{
char ch1 = tolower(SL[i].fname.at(0));
char ch2 = tolower(SL[i].lname.at(0));
string s3 = SL[i].Id;
stringstream ss;
ss << ch1;
ss << ch2;
ss >> username;
username += s3[3]; //(ch1 << ch2 << s3[3]);
SL[i].usernameL = username;
}
}
return SL;
}
void consolePrint(Student* SL, int size, string username)
{
string categories[] = { "Full Name", "ID", "UN", "Test 1", "Test 2", "Test 3", "Test 4", "Test 5", "Average", "Grade" };
cout << endl;
cout << "Student Grade Report" << endl << endl;
cout << "________________________________________________________________________________________" << endl;
for (int x = 0; x < 10; x++)
cout << categories[x] << " ";
cout << endl;
cout << "________________________________________________________________________________________" << endl;
for (int i = 0; i < size; i++)
{
cout << SL[i].fullName << " " << SL[i].Id << " " << SL[i].usernameL << " " << SL[i].testScore[0] << " " << SL[i].testScore[1] << " " <<
SL[i].testScore[2] << " " << SL[i].testScore[3] << " " << SL[i].testScore[4] << " " <<
SL[i].average << " " << SL[i].grade << endl;
}
cout << "________________________________________________________________________________________" << endl;
float totalAverage = (SL[0].average + SL[1].average + SL[2].average + SL[3].average + SL[4].average) / 5;
cout << "The class average for CS 5 tests is " << totalAverage << endl;
cout << "________________________________________________________________________________________" << endl;
int counta = 0;
int countb = 0;
int countc = 0;
int countd = 0;
int countf = 0;
for (int i = 0; i < size; i++)
{
if (SL[i].average >= 90)
counta++;
if (SL[i].average < 90 && SL[i].average >= 80)
countb++;
if (SL[i].average < 80 && SL[i].average >= 70)
countc++;
if (SL[i].average < 70 && SL[i].average >= 60)
countd++;
if (SL[i].average < 60 && SL[i].average >= 0)
countf++;
}
cout << "The total number of students with grade A is " << counta << endl;
cout << "The total number of students with grade B is " << countb << endl;
cout << "The total number of students with grade C is " << countc << endl;
cout << "The total number of students with grade D is " << countd << endl;
