Write a C++ program to sort an array of integer in ascending order using a function called exchange( ) which accepts two integer arguments by reference.

Write a C++ program to sort an array of integer in ascending order using a function called exchange( ) which accepts two integer arguments by reference.

#include<iostream.h>

#include<conio.h>

void exchange(int (&a)[],int &n);

int main()

{

int a[10],size;

clrscr();

cout<<"Enter the Array size : ";

cin>>size;

cout<<"Enter the Array elements :\n";

for(int i=0;i<size;i++)

cin>>a[i];

exchange(a,size);

cout<<"After sorting :\n";

for(i=0;i<size;i++)

cout<<a[i]<<endl;

getch();

return 0;

}

void exchange(int (&a)[],int &n)

{

for(int i=0;i<n;i++)

for(int j=0;j<n;j++)

if(a[i]<a[j])

{

int temp=a[i];

a[i]=a[j];

a[j]=temp;

}

}

Output:

Enter the Array size: 10

Enter the Array elements :

15

46

89

62

-5

-78

0

5

45

9

After sorting :

-78

-5

0

5

9

15

45

46

62

89
