Question

C programming: Alice, Betty and Carol all vote on 16 separate referenda. Assume that each individual’s vote is represented bitwise in a 16-bit integer, represented in Hexadecimal. Write a function with its signature being short majority(short a, short b, short c) that returns the bitwise majority of the votes. For example, If inputs are 0x8E, 0x21, and 0xD4, the output should be 0x84.

Answer 1

Code

#include<stdio.h>

short majority(short a,short b,short c){

return (a & b) | (b & c) | (c & a);

}

int main(){

int a,b,c; //a,b,c is vote variable,defined as int because %x in scanf is compatible with int

printf("Enter Alice's vote\n");

scanf("%X",&a); //%x takes input in hex format ex-0x8E/0xd4

printf("Enter Betty's vote\n");

scanf("%X",&b);

printf("Enter Carol's vote\n");

scanf("%X",&c);

//pass to majority function by type casting to short

printf("Result of the vote is 0x%X\n",majority((short)a,(short)b,(short)c));

return 0;

}
