Question

Change the the following C++ codes to list the "marks" reported Alphabetically.

---------------------------------------------------------------------------------------------------------

#include <iostream>
#include<string.h>
using namespace std;

void display(int marks[10]);

int main()
{
int marks[10];

int i;x
for (i=0; i<10; i++)
{

cout << "Enter marks : ";
cin >> marks[i];
}

display(marks);

return 0;
}

// Create the function sort to sort the marks in alphabetical order

void display(int marks[10])
{

cout <<"Displaying marks in Ascending Order " << endl;

for (int i = 0; i <10; ++i)
{
cout<< marks[i] << " " <<endl;

}

}

#include <iostream>
#include <string.h>

using namespace std;

void swap(char *a, char *b )
{
   char temp = *a;
   *a = *b;
   *b = temp;
}

void sort(char *word)
{
   for (unsigned int i = 0; i < strlen(word) - 1; i++)
       for (unsigned int j = i + 1; j < strlen(word); j++)
           if (word[i] > word[j])
               swap(&word[i], &word[j]);
}

int main()
{
   char marks[10];
   int i;
   for (i=0; i<10; i++)
    {
        cout << "Enter marks : ";
        cin >> marks[i];
    }
   sort(marks);
   cout << marks;

   return 0;
