amazing

so did you remove the two ifs if so

can you compile now

[tawdry tartan]

yes, but the error now is "terminating with uncaught exception of type std::invalid_argument: stoi: no conversion
: abort"

[rugged quarry]

send the code again

[tawdry tartan]

 //if option ==1
        else if (option == 1){
            string filename;
            cout << "Enter name of file: ";
            cin >> filename;
            if (filename == "COP1334C.txt"){
                ifstream myfile(filename);
                if (myfile) {
                    while (getline(myfile, line)) {
                        cout << line << '\n';

                        //calculate the average of numbers
                         count +=1;
                        average +=std::stoi(line);

[rugged quarry]

okay are the lines printed?

[tawdry tartan]

yes, i think so

[rugged quarry]

wdym you think so you either see them or you dont

because that error says something has gone wrong converting the string to an int

[tawdry tartan]

i see them....

[rugged quarry]

can you show me the output?

[tawdry tartan]

like this? Choose one of the following options
1.Process Grades Summary report
2.Quit
Option:
1
Enter name of file: COP1334C.txt
COP1334C - Introduction to C++ Programming
libc++abi: terminating with uncaught exception of type std::invalid_argument: stoi: no conversion: abort

[rugged quarry]

so COP1334C - Introduction to C++ Programming
is indeed in the file

obviously when converting a string to an int

and the string is a string

its a bit messy

how many lines are there that dont have the numbers?

[tawdry tartan]

about 22 or so

[rugged quarry]

                    int skip = 0;  
                    while (getline(myfile, line))
                    {
                        cout << line << '\n';
                        skip++;

                        
                        if (skip <= 22)
                          continue;
                        
                        // calculate the average of numbers
                        average += std::stoi(line);
                    }

so try this

this will try and skip the first 22 lines

[tawdry tartan]

the numbers are all mixed up

for example:

grade, name, grade, name

[rugged quarry]

no man we will finish this in 5hrs im sorry but for that i dont have time, please work on that yourself, id first start by calculating the avg correctly, for reading every second grade you can use the skip count and then like skip % 2 == 0 .. (odd/even)

[tawdry tartan]

i will do that, thanks for the help. i appreciate it.
