SORT AN ARRAY OF INTEGER IN ASCENDING ORDER USING A FUNCTION BY REFERENCE
hello friends....
TAKE THE FIRST STEP TO KNOWLEDGE FRIENDS BECAUSE KNOWLEDGE IS FREE.
/* 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 (&)[], int &);
void main()
{
int a[20],n,i;
clrscr();
cout<<"enter store elements :";
cin>>n;
cout<<"enter elements :"<<endl;
for(i=0; i<n; i++)
{
cin>>a[i];
}
exchange(a,n);
cout<<"\n";
for(i=0; i<n; i++)
{
cout<<"a["<<i<<"]="<<a[i]<<endl;
}
getch();
}
void exchange(int (&x)[], int &y)
{
int i,j,temp;
for(i=0; i<y; i++)
for(j=i+1; j<y; j++)
{
if(x[i]>x[j])
{
temp=x[i];
x[i]=x[j];
x[j]=temp;
}
}
}
OUTPUT
===============
enter store elements :7
enter elements :
50
20
40
55
22
68
48
a[0]=20
a[1]=22
a[2]=40
a[3]=48
a[4]=50
a[5]=55
a[6]=68
