Question
can be answered in c, cpp, h, txt, java, zip, and py. I prefer c++ as it's the language I'm most proficient in. I have my truth table calculated, but not sure where to start in the coding. I've coded a truth table before, but it was only 2 variables. Not sure how to go about starting out with this many variables.
Print the truth table for the following propositional statement using the variables a, b, c, d, e:
(( c V ~d ) A b ) A ~( d V a A e )
Note: V represents OR, A represents AND, ~ represents NOT
The truth table should include 6 columns: a, b, c, d, e and answer.
Output should contain 33 rows:
The first row should display column headers (using the correct symbols). The last 32 rows should contain the values of the truth table.
To make this program easier to read and grade, format the 5 propositional variables as follows:
a: toggle between 16 T then 16 F
b: toggle between eight T then eight F
c: toggle between four T then four F
d: toggle between two T then two F
e: toggle between one T then one F
Do not hardcode the truth values. They must be calculated.
Explanation / Answer
// this is a generic code for printing truth table of any number of variables. juts we need to change the No_of_variables value.
// as currently it is set to 5.
public class Demo {
//all varibales are defined as integers so that we can use this as index in to array at line 25
static int a=0;
static int b=1;
static int c=2;
static int d=3;
static int e=4;
public static void main(String args[]) {
int no_Of_variables = 5;
System.out.println("a| b| c| d| e| Result|");
truthTable(0, no_Of_variables, new int[no_Of_variables]);
}
private static void truthTable(int index, int varLength, int[] current)
{
if (index == varLength)
{
for (int i = 0; i < varLength; i++)
{
System.out.print(current[i] + "| ");
}
System.out.print((( current[c] | ~current[d] ) & current[b] ) & ~( d | a & e ));//line 25
System.out.print(" |");
System.out.println();
} else
{
for (int i = 0; i < 2; i++)
{
current[index] = i;
truthTable(index + 1, varLength, current);
}
}
}
}
please check code and run it with java compliler.
