    Lowest score drop assignment

    Hello everyone, I am having a problem to program this assignment. (I've looked in my C++ book and searched these boards and google other forums already, but nothing I've found explains that help me to solve the problem.) My problem is that after I input the getScores. I get a break or continue error and fail to build the program. I think the problem was the "findLowest" or "calcAverage" part in the code. Here is an error that I got: (error C3861: "findLowest": identifier not found.) I almost finish the assignment, but this error keeps failing me. I hope someone could explain the problem to me, and guide me how to work on this problem/error. Thank you, and I would really appreciate you very much.

    Here is the following assignment question:

    Write a program that calcuates the average of a group of 5 test scores, where the lowest score in the group is dropped. Your program should use the following functions:

    • getScore( ) should ask the user for a test score, store it in a reference variable, and validate it. This function should be called by main once for each of the five scores.
    • calcAverage( ) should calculate and display the average of the four highest scores. This function should be called just once by main, and should be passed the five scores.
    • findLowest( ) should find and return the lowest of the five scores passed to it. It should be called by cacAverage, which uses the function to determin which of the five scores to drop.

    Input Validation: Do not accept test scores lower than 0 or higher than 100


    And here is the code:


    Code:
    .
    #include <iostream>
    #include <iomanip>
    using namespace std;
     
    // Function prototype
    void getScore(int &);
    void calcAverage(int, int, int, int, int);
    int fineLowest(int, int, int, int, int);
            
    int main()
    {
             int testScr1, testScr2, testScr3, testScr4, testScr5;
            
            
             getScore(testScr1);
             getScore(testScr2);
             getScore(testScr3);
             getScore(testScr4);
             getScore(testScr5);
     
             calcAverage(testScr1, testScr2, testScr3, testScr4, testScr5);
     
     
    system("PAUSE");
    return 0;
    }

    .

    (P.s. I am a newcomer to this website, and also a newbie in c++ programming field.)

    Remove all the else's from findLowest.

    Something like
    Code:
             if (s2 < lowest )       
             {
                      lowest = s2;
             }
             if (s3 < lowest)
             {
                      lowest = s3;
             }
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Hi Salem, thanks for your response to help me on this assignment, and sorry for the late reply. But I still got the same error (error C3861: "findLowest": identifier not found.) after I remove the else's.

    Prototype:
    int fineLowest(int, int, int, int, int);

    Definition:
    int findLowest(int s1, int s2, int s3, int s4, int s5)

    And while you're at it, read: SourceForge.net: Do not remove parameter names - cpwiki
    Learning how to use arrays and loops wouldn't be a bad idea, either.
