Sort an array of integer in ascending order

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
