"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(int 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.

            {
               nHighest = a [i]; 
            }

Can you post your full code?

Here is the full code:

/*Defines a global constant called N throughout the file.

*/

#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

*/
class StudentScores
{
private:
int _scores[N];
public:
StudentScores(int 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[] = {1,29,31,45,5,61,99,87,12,100};

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

//Use the getHighestScore method to display the highest score
cout << "The highest score is " <<
studentOne.getHighestScore() << endl;
cout << "The lowest score is " <<
studentOne.getLowestScore() << endl;
cout << "The average score is " <<
studentOne.getAverageScore() << 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
