C program for selection sort:
#include <stdio.h>
int main()
{
int i, j, num, arr[250], pos, temp;
printf(“Enter number of elements\n”);
scanf(“%d”, &num);
printf(“Enter %d integers\n”, num);
for ( i = 0 ; i < num ; i++ )
scanf(“%d”, &arr[i]);
for ( i = 0 ; i < ( num – 1 ) ; i++ )
{
pos = i;
for ( j = i + 1 ; j < num ; j++ )
{
if ( arr[pos] > arr[j] )
pos = j;
}
if ( pos != i )
{
temp = arr[i];
arr[i] = arr[pos];
arr[pos] = temp;
}
}
printf(“Selection sorting in ascending order:\n”);
for ( i = 0 ; i < num ; i++ )
printf(“%d\n”, arr[i]);
return 0;
}
Output:
