this is the question given by my lecturer :-
Write a program to accept 5 students (names) and their respective test marks into an array or arrays. Sort them and print the lists in:

a) alphabetical order
b) mark ranks(from highest to lowest)

and my input is

enter name : jay
enter marks : 14
enter name : bay
enter marks :10
enter name : hay
enter marks : 13
enter name : ray
enter marks : 11
enter name : say
enter marks : 12

    #include <iostream>
    using namespace std;

    void selectionSort(string [],int[], int);
    void showArray(string [],int[], int);
    void entah(string [],int[],int);


    int main()

        const int SIZE = 5;

        int num[5];
        string name[5];
        for(int n=0;n<5;n++)
        {
            cout<<"enter name:";
            cin>>name[n];
            cout<<endl;
            cout<<"enter the marks:";
            cin>>num[n];
            cout<<endl;
        }


        selectionSort(name,num, SIZE);
        cout << "\n\tThe alphabetically sorted string is: \n";
        showArray(name,num, SIZE);
        cout << "\n\tThe mark sorted list is: \n";
        entah(name,num,SIZE);

        return 0;
    }


    void selectionSort(string name[],int num[], int elems)
    {
        int startScan, minIndex;
        string strName;
        int strNum;
        for(startScan = 0; startScan < (elems - 1); startScan++)
        {
            minIndex = startScan;
            strName = name[startScan];
            strNum = num[startScan];
            for(int index = startScan + 1; index < elems; index++)
            {
                if(name[index] < strName)
                {
                    strName = name[index];
                    strNum = num[index];
                    minIndex = index;
                }
            }
            name[minIndex] = name[startScan];
            num[minIndex] = num[startScan];
            name[startScan] = strName;
            num[startScan] = strNum;
        }
    }


    void showArray(string name[],int num[], int elems)
    {
        for(int i = 0; i < elems; i++)
            {
            cout << i << ": " << name[i]  << "\t" << num[i] << endl;
            }
    }

    void entah(string name[],int num[],int elems)
    {

        for(int i = 0; i < 5; i++)
        {
            for(int j = i + 1; j < 6; j++)
            {
                if(num[i] < num[j])
                {

                    int temp = num[i];
                    num[i] = num[j];
                    num[j] = temp;
                }
            }
        }
        for(int k =0; k < 5 ; k++)
            {
            cout << k << ": " << num[k]  << "\t" << name[k] << endl;
            }
    }

after build and run,

the result i get is

alphabetically
0:bay 10
1:hay 13
2:jay 14
3:ray 11
4:say 12
sorted by marks
0:14 bay
1:13 hay
2:12 jay
3:11 ray
4:10 say

what i suppose to get in the results are these:

alphabetically
0:bay 10
1:hay 13
2:jay 14
3:ray 11
4:say 12
sorted by marks
0:14 jay
0:13 hay
0:12 say
0:11 ray
0:10 bbay

help me please..

Well, I'm not going to do your homework for you. However, you should look closely at your numeric sorting function. It sorts the numbers, but it's missing something important.
