Write a C++ program to sort an Array in Ascending order.
Example 1: Without using function
Program Code for run:
#include
<iostream>
using
namespace std;
int
main()
{
int a[20], n, i, j, temp;
clrscr();
cout << ” How many
elements to enter in array ” << endl;
cin >> n;
cout << ” Enter elements
of an array ” << endl;
for ( i = 0 ; i < n ; i ++)
cin >> a[i];
cout << ” Display
elements of an array: Before Sort ” << endl;
for ( i = 0 ; i < n ; i ++)
cout << ”
a[” << i << “]:= ” << a[i] << ” \t
“;
for ( i = 0 ; i < n ; i ++)
{
for ( j = i ; j < n ;
j ++)
{
if(a[i] >= a[j])
{
temp
= a[i];
a[i] = a[j];
a[j] = temp;
}
}
}
cout << ” Display
elements of an array: After Sort ” << endl;
for ( i = 0 ; i < n ; i ++)
cout << ”
a[” << i << “]:= ” << a[i] << ” \t
“;
return 0;
}
Output
of Program:
How
many elements to enter in array
5
Enter
elements of an array
19
12
15
13
16
Display
elements of an array: Before Sort
a[0] :=
19 a[1] := 12 a[2] := 15 a[3] :=
13 a[4] := 16
Display
elements of an array: After Sort
a[0] :=
12 a[1] := 13 a[2] := 15 a[3] :=
16 a[4] := 19
Example 2: Using function
Program
Code for run:
#include
<iostream>
using
namespace std;
void
sortArray(int *a, int n)
{
int temp;
for ( int i = 0 ; i < n ; i ++)
{
for ( int j = i ; j <
n ; j ++)
{
if(*(a+i)
>= *(a+j))
{
temp
= *(a+i);
*(a+i)
= *(a+j);
*(a+j)
= temp;
}
}
}
}
int
main()
{
int a[20], n, i, j;
clrscr();
cout << ” How many
elements to enter in array ” << endl;
cin >> n;
cout << ” Enter elements
of an array ” << endl;
for ( i = 0 ; i < n ; i ++)
cin >> a[i];
cout << ” Display
elements of an array: Before Sort ” << endl;
for ( i = 0 ; i < n ; i ++)
cout << ”
a[” << i << “]:= ” << a[i] << ” \t
“;
sortArray(a,n); // call function
cout << ” Display
elements of an array After Sort ” << endl;
for ( i = 0 ; i < n ; i ++)
cout << ”
a[” << i << “]:= ” << a[i] << ” \t
“;
return 0;
}
Output
of Program:
How many elements to
enter in array
5
Enter
elements of an array
19
12
15
13
16
Display
elements of an array: Before Sort
a[0] :=
19 a[1] := 12 a[2] := 15 a[3] :=
13 a[4] := 16
Display
elements of an array: After Sort
a[0] :=
12 a[1] := 13 a[2] := 15 a[3] :=
16 a[4] := 19
