C program to sort an array using selection sort

#include <stdio.h>
#define N 100
void sort(int [],int);
main()
{
int i,n;
int a[N];
printf("Enter the size of the array\n");
scanf("%d",&n);
printf("Enter the numbers...\n");
for(i=0;i<n;i++)
scanf("%d",&a[i]);
sort(a,n);
printf("Sorted array is....\n");
for(i=0;i<n;i++)
printf("%2d\n",a[i]);
}
void sort(int a[],int n)
{
int i,j,t;
for(i=0;i<n;i++)
{
for(j=i;j<n;j++)
{
if(a[j]<a[i])
{
t=a[i];
a[i]=a[j];
a[j]=t;
}
}
}
}
