Even/Odd issues

[akemikanegae]

Everything works, except there is something wrong with the even/odd calculations...it gives weird numbers. Any ideas??

#include <stdio.h>
#include <stdlib.h>
#define N 9 /* MAIN */


void revArray(int arr[])
{
int temp[N];
int i;
for(i = 0; i < N; ++i)
{
temp[i] = arr[N - 1 -i];
}
for(i = 0; i < N; ++i)
{
arr[i] =temp[i];
}
}
int *revElement(int arr[])
{
static int idx = N;
idx = --idx;
return arr + idx;
}
void evenOdd(int odd[])
{
int i;
int evenTemp[N/2];
int oddTemp[(N-1)/2];

char tempOdd;
for(i=0; i<(N-1)/2; i++)
{
if(odd[i]%2 == 0) /* if even integer*/
evenTemp[i] = odd[i]; /*store even numbers temporary */
else
oddTemp[i]= odd[i]; /*store odd numbers temporary */
}

for(i=0; i<(N-1)/2; i++)
{
odd[i]=evenTemp[i]; /*swap even numbers first in the array*/
odd[N-1-i]=oddTemp[i]; /*swap odd numbers last in the array */

}
}



int main(int argc, char **argv)
{


int a[N];
int idx;
int *p = a;
while(p < a + N) *p++ = a + N - p;
printf("Original: ");
p = a;
while(p < a + N)
printf("%2d ",*p++); /* Part A: Reverse the array */

revArray(a);
printf("\nReversed: ");
p = a; while(p < a + N)
printf("%2d ",*p++);
printf("\n"); /* Part B: Return elements in reverse order */

printf("Original: ");
for (idx = 0; idx < N; idx++) {
printf("%2d ",*revElement(a));
}
printf("\n"); /* Part C: Put even numbers first, odd numbers last in the array. Order of
the elements is not important as long as all evens are before first odd */

printf("Even: ");
evenOdd(a);
p = a;
while(p < a + N)
printf("%2d ",*p++);
printf("\n");
system("pause");
