Thread: Assignment Help

Hello, I'm a newbie in c programming. Can someone help me on this assignment. The code is what I have done so far: part_2.c



PART2: Bit Masking (3 marks)

1. Initialize an 8-bit binary number (call it num1) that equals the last digit of your student#.
2. Initialize a binary mask (call it mask1) that equals the next digit (before the last) of your student#.
3. Your code should implement the following:

1. OR mask1 with num1, print the result
2. toggle num1, print the result

To check part (a): use num1=0b00000101 and mask1= 0b00000010. The result is 7
To check part (b): for the same num1, result is -6

1. In the space below, attach a screenshot of the code and the results window.

Code:

#include<stdio.h>
void bit_mask(unsigned char x) {
    unsigned char m = 0x80;
    for ( ; m; m >>= 1){
        putchar(x & m ? '1' : '0');	
	}	
    putchar('\n');
}

int part_2() {
    char a[] = "4";
    unsigned char b[4];
	size_t i;
	for (i = 0; i < 2; i++){
    	b[i] = a[i] - '0';
	}
    for (i = 0; i < 2; i++){
        bit_mask(b[i]);	
	}	
    return 0;
}
