Selection Sort in c
The idea of Selection Sort is rather simple. It basically determines the minimum (or maximum) of the list and swaps it with the element at the index where its supposed to be. The process is repeated such that the nth minimum (or maximum) element is swapped with the element at the n-1th index of the list. The below is an implementation of the algorithm in C.
PROGRAM:
#include <stdio.h>
int main()
{
int data[100],i,n,steps,temp;
printf("Enter the number of elements to be sorted: ");
scanf("%d",&n);
for(i=0;i<n;++i)
{
printf("%d. Enter element: ",i+1);
scanf("%d",&data[i]);
}
for(steps=0;steps<n;++steps)
for(i=steps+1;i<n;++i)
{
if(data[steps]>data[i])
/* To sort in descending order, change > to <. */
{
temp=data[steps];
data[steps]=data[i];
data[i]=temp;
}
}
printf("In ascending order: ");
for(i=0;i<n;++i)
printf("%d ",data[i]);
return 0;
}OUTPUT:
Enter the number of elements to be sorted: 5
1. Enter element: 12
2. Enter element: 1
3. Enter element: 23
4. Enter element: 2
5. Enter element: 0
In ascending order: 0 1 2 12 23
