Can anybody tell me why is this array giving me corruption?

/* Program begins */
#include <stdio.h>
#include <time.h>
#include <stdlib.h>

void sort (int a[], int n);

int main (void)
{

	int i, j, k, nums[ 60 ];

	srand( ( int ) time( NULL ) ) ;

	for ( i = 0; i < 60; i++ )
		nums[ i ] = i;

	for ( i = 0 ; i < 60 ; i++ )
	{
		j = ( rand() % 60 ) + 1 ;
		k = nums[ i ] ;
		nums[ i ] = nums[ j ] ;
		nums[ j ] = k ;
	}



	printf( "Six random numbers are: \n") ;
	for ( i = 0 ; i < 6 ; i++ )
		printf("nums[%i] = %i\n", i, nums[i]);
	
	sort (nums, 6);
	printf("\n");
	
	for ( i = 0 ; i < 6 ; i++ )
		printf("nums[%i] = %i\n", i, nums[i]);

	return 0;
}

void sort (int a[], int n)
{
	int i, j, temp;
	for ( i = 0; i < n - 1; ++i )
		for ( j = i + 1; j < n; ++j )
			if ( a[i] > a[j] ) {
				temp = a[i];
				a[i] = a[j];
				a[j] = temp;
			}
}

/* Program ends */

There are just 60 random numbers (1 to 60) out of which I am selecting 6 and sorting them but the corruption occurs in VS2010.

I tried using 61 instead of 60 but the problem doesn't go away!!

I am accessing the numbers using the index numbered 0 to 5 (6 numbers here).
