I'm stuck on how I can creat a LE object and pass it the line just input..than could i use a for loop and the .push_back to get the lines into the vector?
vector<Log_Entr y> parse(string);
This function does the following:
Open a log file specified by the parameter name (File I/O).
Read lines from the opened file.
Create a Log_Entry object passing the line just input.
Push each Log_Entry object...

ok i got it to work with :
but my output is 85.4714 for the...Code:double ret_avg(float scores[], int num_scores, int tot_pts) { double sum = 0; double avg = 0; avg = 0; for (int i = 0; i < num_scores; i++) { sum = scores[i] + sum; } avg = sum / tot_pts; avg = avg * 100; return (avg); }Leave a comment:

heres what i currently have in my code: the function is just printing out a 0 for the quizzes for both students.
...Code:const int tot_quiz = 7; const int tot_proj = 6; const int tot_exam = 2; const int tot_labs = 14; const int tot_quiz_pts = 70; const int tot_proj_pts = 300; const int tot_exam_pts = 200; const int tot_lab_pts = 150; double ret_avg(float scores[], int num_scores,

whats wrong with my function?
Ok everything is good...I read in all my grades into each of the different arrays that they need to go in. Now Im trying to write a function that takes the grades and computes the average on a hundred point scale...for example:
Student 1
7 quiz scores 9 9.33 8 10 5.5 8 10 ==> the 5.5 score should be dropped, returned value: 90.55
6 project scores 20 47.5 47 45 47.5 48 ==> returned value: 94.44

converting the string of a file to a float
Okay, Im having some problems with my code. Im trying to use the <cstdlib> library and im trying to convert string data at each whitespace slot. I think if you see my code you'll get what im trying to do :
