Please write a code and a answer of the question below.
Write a C program that prompts the user to enter three integers a, b, c, and then computes the results of the following logical operations, in sequence:
!a || !b++ && c
(a-1 || b/2) && (c*=2)
(a-- || --b) && (c+=2) a || !(b && --c)
Here are three sample runs of this a program.
-----------------------------------
Enter integers a, b, c: 1 1 1
!a || !b++ && c: False
(a-1 || b/2) && (c*=2): True
(a-- || --b) && (c+=2): True
a || !(b && --c): False
--------------------------------------
Enter integers a, b, c: -7 42 0
!a || !b++ && c: False
(a-1 || b/2) && (c*=2): False
(a-- || --b) && (c+=2): True
a || !(b && --c): True
---------------------------------
Enter integers a, b, c: 10 0 1000
!a || !b++ && c: True
(a-1 || b/2) && (c*=2): True
(a-- || --b) && (c+=2): True
a || !(b && --c): True
--------------------------------------------
Are there values of a, b, and c that would make all the results False? Submit your answer to this question as a comment in your program. Please explain clearly how you have arrived at this answer. (Hint: It may be useful to start with the last expression and work backwards)
Solution
#include<stdio.h>
int main()
{
//declare variable a, b , c
int a, b, c;
//ask user to input
printf(\"Enter three integers a, b, c: \");
scanf(\"%d%d%d\", &a, &b, &c);
if (!a || !b++ && c)
printf(\" !a || !b++ && c: True\ \");
else
printf(\" !a || !b++ && c: False\ \");
if ((a - 1 || b / 2) && (c *= 2))
printf(\"(a - 1 || b / 2) && (c *= 2): True\ \");
else
printf(\"(a - 1 || b / 2) && (c *= 2): False\ \");
if ((a-- || --b) && (c += 2))
printf(\"(a-- || --b) && (c += 2): True\ \");
else
printf(\"(a-- || --b) && (c += 2): False\ \");
if (a || !(b && --c))
printf(\"a || !(b && --c): True\ \");
else
printf(\"a || !(b && --c): False\ \");
}

a || !(b && --c): True
