Question

3. Write a program that inputs 4 hexadecimal digits as strings (example 7F), converts the string digits to a long – use strtol(input string,&ptr,base) to do the conversion. Just declare ptr as a char ptr, don’t worry about what it does. Copy each converted number [ a long] into unsigned char’s [like the variable num1 below – hint: cast a long variable into the unsigned char’s] before performing the following logical operations on them (parenthesis might help, since things should be executed from left to right): result=num1 and num2 or num 3 exclusive or num4 print out result in capital hex (15 points)

Answer 1

#include <stdio.h>

#include <stdlib.h>

int main()

numb3)^numb4;

//Printing the result in capital hex ("%X" take care of this).

printf("%X",result);

return 0;

Code OUTPUT

Enter the first hexadecimal number: 1 Enter the second hexadecimal number:2

Enter the third hexadecimal number: 3 Enter the fourth hexadecimal number: 4 Resultant Value: 7 Process returned o (0×0) execution time : 3.076 s
