Hello,
I was just coding and ran into a little logic problem which is as follows:
There are two booleans/variables which can be either false or true.
The desired thrutle table is:
A = input
B = input
C = output
A B C:
-------
F F T
F T F
T F T
T T T
Seems simple enough: C == A || !B
18:38 $ cat testlogic.c
#include <stdio.h>
#include <stdlib.h>
/*
** A = input
** B = input
** C = output
**
** A B C:
** -------
** F F T
** F T F
** T F T
** T T T
*/
int testlogic(int a, int b)
{
return (a || !b);
}
int main(void)
{
/* A B C */
int ttable[4][3] = { {0,0,1}, /* F F T */
{0,1,0}, /* F T F */
{1,0,1}, /* T F T */
{1,1,1} /* T T T */
};
int rc = EXIT_SUCCESS;
int i, max;
for (i = 0, max = sizeof(ttable) / sizeof(ttable[0]); i < max ; ++i)
if (testlogic(ttable[i][0],ttable[i][1]) != ttable[i][2])
{
printf("testlogic failed on test %d\n",i);
rc = EXIT_FAILURE;
}
if (rc == EXIT_SUCCESS) puts("SUCCESS");
return rc;
}
18:39 $ cc -o testlogic testlogic.c
18:39 $ ./testlogic
SUCCESS
Strangest looking Python I've ever seen. Or is it a case of "Get thee
behind me, Satan" :)

My fellow Pythonistas, ask not what our language can do for you, ask
