The even/odd function does not work...here is what I have so far. Everything works except for the evenodd function. I am supposed to get the even numbers to list first, then the odd numbers. It should look like this:
Original: 9 8 7 6 5 4 3 2 1
Reversed: 1 2 3 4 5 6 7 8 9
Original: 9 8 7 6 5 4 3 2 1
Even: 2 4 6 8 5 3 7 9 1
Code:
#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 */
elseoddTemp[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");
}
