Question

In this assignment you will transform that program into a function with the following prototype bool xor(bool a, bool b)
As in your original program, xor returns the exclusive or of a and b. Then write a program that calls xor for all four possible combinations of a and b( false-false, false- true, etc) The output of that program is a table with three columns a, b, and xor, appropriately labeled and the results of all four combinations listed:

a b xor(a,b)

Answer 1

C Code:

#include<stdio.h>
#include<stdbool.h>

//Function Declaration
bool xor(bool a, bool b);

int main() {
   int v,w;
   bool a[]= {false, true};
   bool b[]= {false, true};
   printf("a       b      a xor b ");
   printf("-------------------------- ");
   for(v= 0; v<=1; v++){
       for (w= 0; w<=1; w++){
           // calling the function automatically for all the combinations between a and b

           // I used 2 for loops to get all the combinations of boolean variables a and b
           bool x = xor(a[v],b[w]);
           printf(a[v] ? "true " : "false");
           printf("   ");
           printf(b[w] ? "true = " : "false = ");
           printf(x ? "true " : "false ");
       }
   }
  
   return 0;
}

// function for the XOR operator
bool xor(bool a, bool b){
    // ^ operator gives the xor results between two boolean variables
    return a^b;
}

Output:
