Issues with formula

[michael1320]

HI I am building a program that will take in assignment, quiz, exams, and final exams and calculate the percentage. The code is not complete so there are a couple things not operating. My percent's are not showing up for quizzes and exams and are not being called into my perc function.

#include <stdio.h>
#include <stdlib.h>


const int MAX = 100;
const int ASSIGN_TOTAL = 7, QUIZ_TOTAL = 3, EXAMS_TOTAL = 2;
const int ASSIGN_MAX = 100, QUIZ_MAX = 25, EXAMS_MAX = 100, FINAL_MAX = 100;


int main()
{
    char name[MAX];
    int assigns[ASSIGN_TOTAL], quizzes[QUIZ_TOTAL], exams[EXAMS_TOTAL], finalExam;
    double assignsMedian, assignsMean, assignsPerc;
    double quizzesMedian, quizzesMean, quizzesPerc;
    double examsMedian, examsMean, examsPerc, finalPerc, classPerc, classGrade;

    do
    {
        readName(name);

        fillArray(assigns, ASSIGN_TOTAL, "assignments");
        selectionSort(assigns, ASSIGN_TOTAL);
        assignsMedian = findMedian(assigns, ASSIGN_TOTAL);
        assignsMean = findMean(assigns, ASSIGN_TOTAL);
        assignsPerc = calcPercentage(assigns, ASSIGN_TOTAL, ASSIGN_MAX);


        fillArray(quizzes, QUIZ_TOTAL, "quizzes");
        selectionSort(quizzes, QUIZ_TOTAL);
        quizzesMedian = findMedian(quizzes, QUIZ_TOTAL);
        quizzesMean = findMean(quizzes, QUIZ_TOTAL);
        quizzesPerc = calcPercentage(quizzes, QUIZ_TOTAL, QUIZ_MAX);


        fillArray(exams, EXAMS_TOTAL, "exams");
        selectionSort(exams, EXAMS_TOTAL);
        examsMedian = findMedian(exams, EXAMS_TOTAL);
        examsMean = findMean(exams, EXAMS_TOTAL);
        examsPerc = calcPercentage(exams, EXAMS_TOTAL, EXAMS_MAX);


        //finalExam = readFinalScore();
        //finalPerc = calcFinalPercentage(finalExam, FINAL_MAX);

        classPerc = calcClassPerc(assignsPerc, quizzesPerc, examsPerc, finalPerc);
        //classGrade = calcGrade(assignsPerc, quizzesPerc, examsPerc, finalPerc);

Please read the CB Rules. http://forums.next.codeblocks.org/index.php/topic,9996.0.html

I saw no question in your post; so, you might wish to post one after reading the rules.

HI I am building a program that will take in assignment, quiz, exams, and final exams and calculate the percentage. The code is not complete so there are a couple things not operating. My percent's are not showing up for quizzes and exams and are not being called into my perc function.

Can anyone take a quick look and see if there is anything popping out that may be wrong.

Thanks Michael

The main problem seems to be you can NOT read the rules and follow them.
