3.5.3 Booleans Homework Hack

Homework Hack

Create a Logic Gates Simulator in Python and Java this demonstrates how different logical operations (AND, OR, NOT, NAND, NOR, XOR) work with various inputs. This can visually represent how truth tables function.

Logic Gate Simulator in Python

def AND(A, B):
    return A and B

def OR(A, B):
    return A or B

def NOT(A):
    return not A

print("A     B | AND | OR | NOT A")
print("---------------------------")
for A in [True, False]:
    for B in [True, False]:
        print(f"{A:<5} {B:<5} | {AND(A, B):<4} | {OR(A, B):<3} | {NOT(A)}")

A     B | AND | OR | NOT A
---------------------------
1     1     | 1    | 1   | False
1     0     | 0    | 1   | False
0     1     | 0    | 1   | True
0     0     | 0    | 0   | True

Logic Gate Simulator in Javascript

%%javascript

// Define logic gate functions
function AND(A, B) {
    return A && B;
}

function OR(A, B) {
    return A || B;
}

function NOT(A) {
    return !A;
}

function NAND(A, B) {
    return !(A && B);
}

function NOR(A, B) {
    return !(A || B);
}

function XOR(A, B) {
    return A !== B;
}

// Display the results of the logic gates
function displayGateOperations(A, B) {
    console.log("A: " + A + ", B: " + B);
    console.log("AND: " + AND(A, B));
    console.log("OR: " + OR(A, B));
    console.log("NOT A: " + NOT(A));
    console.log("NAND: " + NAND(A, B));
    console.log("NOR: " + NOR(A, B));
    console.log("XOR: " + XOR(A, B));
    console.log("-----------------------------");
}

// Main logic gate simulator function
function logicGateSimulator() {
    console.log("Logic Gate Simulator");
    console.log("Enter 'exit' to quit");

    while (true) {
        let A_input = prompt("Enter value for A (true/false): ").trim();
        if (A_input.toLowerCase() === "exit") {
            break;
        }

        let B_input = prompt("Enter value for B (true/false): ").trim();
        if (B_input.toLowerCase() === "exit") {
            break;
        }

        // Convert inputs to boolean
        let A = (A_input.toLowerCase() === 'true');
        let B = (B_input.toLowerCase() === 'true');

        // Display the results
        displayGateOperations(A, B);
    }
}

// Run the logic gate simulator
logicGateSimulator();
