Right Projection (or Projection Q), is a part of programming logic that always returns the right-side value in a Truth table. That is to say, for values P and Q in a truth table, the right projection always reflects the value (or state, if Boolean) of q.

To put it visually, where X is the right projection of (p, q):

Contradiction/Falsehood: Setting every bit to 0; Outputting logically false to all possible logical inputs.

Demonstration of the indicated keyword.

If you wish to aid your definition with a code sample, you can do so by using a wiki code block, an example follows:

/*
 * 
 */
#include <stdio.h>
#include <stdlib.h>
 
// program to always output false where false = 0
 
char false(char, char);
//function prototype
 
int main( )
{
 char p = 0;
 char q = 0;
 char result = 0;
 
printf("P  |   Q   |   X  \n");
printf("------------------\n");
printf("%d  |   %d   |   %d \n", p, q, false(p, q));
 
 q = 1;
 
printf("%d  |   %d   |   %d \n", p, q, false(p, q));
 p = 1;
 q = 0;
 
printf("%d  |   %d   |   %d \n", p, q, false(p, q));
 
 p = 1;
 q = 1;
 
printf("%d  |   %d   |   %d \n\n", p, q, false(p, q));
 
printf("Input P: \n");
scanf("%hhd", &p);
printf("Input Q: \n");
scanf("%hhd", &q);
 
scanf("%hhd", &q);
result = false(p, q);
printf("Result is: %hhd\n\n", result );
 
 
return(0);
 
}
 
//function definition
char false(char a, char b)
{
char x;
if(b==1)
  x=0;
else if(b==0)
  x=0;
return(x);
