You Gotta try this...

This is a SORT example and here's the output:

Before shellsort: 83 86 77 15 93 35 86 92 49 21
After shellsort: 15 21 35 49 77 83 86 86 92 93

Try this or your own code, of course...


#include <stdio.h>

#define MAXARRAY 10

void shellsort(int a[], int total, int index);

int main(void) {
int array[MAXARRAY] = {0};
int i = 0;

/* load some random values into the array */
for(i = 0; i < MAXARRAY; i++)
array[i] = rand() % 100;

/* print the original array */
printf("Before shellsort: ");
for(i = 0; i < MAXARRAY; i++) {
printf(" %d ", array[i]);
}
printf("\n");

shellsort(array, MAXARRAY, 1);

/* print the `shellsorted' array */
printf("After shellsort: ");
for(i = 0; i < MAXARRAY; i++) {
printf(" %d ", array[i]);
}
printf("\n");

return 0;
}

void shellsort(int a[], int total, int index) {
int i = 0;
int j = 0;
int k = 0;
int l = 0;

for(k = 0; k < index; k++) {
for(i = k; i < total; i += index) {
l = a[i];
for(j = (i - index); j >= 0; j -= index) {
if(a[j] > l)
a[j + index] = a[j];
else
break;
}
a[j + index] = l;
}
}

return;
}
