Thread: help on function defition

> int grades[][exam]

exam is out of scope in that. For that matter, almost all of your variables in your function are, too. Also, main returns int, not void.

That is because you are putting the code for the function inside the main function. You need to move that code outside of the main function. Try this instead:

Code:

#include <iostream.h> 

void top_score(char [][8],char [][8], int [][3], int, int);

void main(void) 
{ 
    const int exam = 3; 
    const int student= 4; 
    char last_name[student][8]; 
    char first_name[student][8]; 
    int scores[student][exam]; 
    int j=0,top,counter=0; 
    float average=0; 

    for(int i=0; i<student; i++)
    { 
        cout<<"Enter first name for student "<<i+1<<": "; 
        cin>>first_name[i]; 
        cout<<"Enter last name for student "<<i+1<<": "; 
        cin>>last_name[i]; 
    }

    for(i=0;i<student; i++)
    { 
        for( j=0;j<exam; j++)
        { 
            cout<<"Enter score #"<<j+1<<"for "<<first_name[i]
                 << " " <<last_name[i]<<": "; 
            cin>>scores[i][j]; 
        } 
        top_score(first_name, last_name, scores, student, exam); 
    } 

    for(i=0;i<student;i++)
    { 
        for(j=0;j<exam;j++)
        { 
            average=average+scores[i][j]; 
            counter++; 
        } 
    } 

    cout<<"\n"<<"The Total Class: Average " << average/counter << endl;

}

void top_score(char first[][8],char last[][8],int grades[][exam],int students,int exams)
{ 

    cout<<endl; 
    top=grades[0][0]; 
    for(i=0;i<students;i++)
    { 
        for(j=0;j<exams;j++)
        { 
            if(grades[i][j]>top) top=grades[i][j]; 
        } 

        cout<<"Student First Name: "<<first_name[i]<<" Student Last Name: "
             <<last_name[i]<<" Top Exam Score: "<<top<<"\n"; 
        top=0; 
    }

}

There may be other errors, but this should address the error you mentioned.

Oh yeah, that too... I shoulda counted more carefully...

Anyways, the errors I talked about are still there.
