Question

Create a C language subroutine

char bin2hex( char N )

that returns the ASCII hex character for the four least significant bits of N.

Answer 1

Answer:- The code is-

#include <stdio.h>

char bin2hex(char N);

int main ()

{

    char N, res;

    printf ("Enter a character:");

    scanf ("%c", &N);

    res = bin2hex(N);

    printf("\nThe ASCII hex value of least four sigificant bit is: %x", res);

    return 0;

}

char bin2hex(char N)

{

    return(N & 0x0F);

}

OUTPUT:-

Enter a character:b

The ASCII hex value of least four significant bit is: 2
