"for" loop to find the highest score in an array.

[lostncland]

I am working on this program. The array has 10 scores. (there is more to this program.) Does the last "for" section make sense?


/*Defines a global constant called N throughout the file.
Note that N = 10.
*/

#define N 10
#include <iostream>
using namespace std;

/*Define a StudentScores class with methods called

(1) getHighestScore – find the highest score in the array
(2) getLowestScore – find the lowest score in the array
(3) getAverageScore – compute the average score

*/
class StudentScores
{
private:
int _scores[N];
public:
StudentScores(i nt scores[])
{
for(int i = 0; i < N; i = i + 1)
_scores[i] = scores[i];
}

int getHighestScore ()
{
int highest;
highest = _scores[0];
for (int i = 0; i < N; i++)
if (a [i]> scores [0]
highest = a [i]
return highest;

Hi,

The code is incomplete.

/*Defines a global constant called N throughout the file. 
Note that N = 10.
*/

#define N 10 
#include <iostream>
using namespace std;

/*Define a StudentScores class with methods called

(1) getHighestScore – find the nHighest score in the array
(2) getLowestScore – find the lowest score in the array
(3) getAverageScore – compute the average score

*/
class StudentScores
{
   private:
      int m_nScores[N];
   
   public:
      StudentScores(int a_nScores[])
      {
         for(int i = 0; i < N; i = i + 1)
         {
            m_nScores[i] = a_nScores[i];
         }
      }

      int GetHighestScore()
      {
         int 
            nHighest = 0;

         nHighest = m_nScores[0];
         for (int i = 0; i < N; i++)
         {
            if (a [i] > a_nScores [0])
            {
               nHighest = a [i]; 
            }
         }
         return nHighest;
      }
};

Can you post your full code?

Here is the full code:

#define N 10
#include <iostream>
using namespace std;

/*Define a StudentScores class with methods called

public:
StudentScores(i nt scores[])
{
for(int i = 0; i < N; i = i + 1)
_scores[i] = scores[i];
}

int getHighestScore ()

int nHighest = 0;
nHighest = m_nScores [0];
for (int i = 0; i < N; i++)
if (a [i] > a_nScores [0];
return nHighest;
{
int getLowestScore( )
{
int lowest;
lowest = _scores[0];
I am supposed to here WRITE A 'while' LOOP THAT DETERMINES THE LOWEST SCORE
return lowest;
}

double getAverageScore ()
{
double ave;
I am supposed to here WRITE A 'for' LOOP THAT COMPUTES THE AVERAGE GRADE
return ave;
}
};

int main(){

//Create a scores array and assign 10 scores
int scores[] = {1,29,31,45,5,6 1,99,87,12,100} ;

//Create a student scores object
StudentScores studentOne(scor es);

//Use the getHighestScore method to display the highest score
cout << "The highest score is " <<
studentOne.getH ighestScore() << endl;
cout << "The lowest score is " <<
studentOne.getL owestScore() << endl;
cout << "The average score is " <<
studentOne.getA verageScore() << endl;
}

Here is the full code:
int getHighestScore ()

int nHighest = 0;
nHighest = m_nScores [0];
for (int i = 0; i < N; i++)
if (a [i] > a_nScores [0];
return nHighest;
{

there are a few errors in the above function, the following should work

int getHighestScore()
{                           // ** added {
int nHighest = 0;
nHighest = _scores [0];     // ** fixed name
for (int i = 0; i < N; i++)
if (_scores  [i] > nHighest) nHighest=_scores  [i];  // ** fixed test
return nHighest;
}                             // ** changed { to }

make sure you are consistent with variable names

now try and complete the rest of the program
