Write a function, reverseDigit, that takes an integer as a parameter and
returns the number with its digits reversed. For example, the value of
reverseDigit(12345) is 54321; the value of reverseDigit(5600)
is 65; the value of reverseDigit(7008) is 8007; and the value of
reverseDigit(-532) is -235.

Write a C program to create a single dimensional array of size 20 and get value from user and store in the array, And Check if there is any zero present in the array. [while giving value give zero).

Write assembly language code that uses a stack frame to implement the following high-level language function and its call. Do not optimize stack access in the function, (i.e.,
write all intermediate results to variables on the stack frame as indicated in the high-level language code).

/* Global variables */
word MemoryWord,
Result;
/* Function */
word IncMemWord (word *Pointer) {
word MemWord;
MemWord = *Pointer;
MemWord = MemWord + 1;
*Pointer = MemWord;
return MemWord;
}
/* Call */
Result = IncMemWord (&MemoryWord);

Explain what the Cortex-M0+ “interrupt priority levels” are and how they are used.

Explain what happens from the time of an interrupt request, (i.e., IRQ line is asserted),
through the start of executing an interrupt service routine, and then how control returns
to the interrupted program. Assume that the interrupt request does not occur at the
same time as any other interrupt request. (Note: ere are many steps involved, so
take your time and be specific.)

Describe the details of initializing the PIT (timer) to generate interrupt requests, as used
in lab. Be sure to describe all control register bits that must be set and/or cleared to
enable interrupts and why each bit/field must have the value that you indicate. (Omit
details of any PIT initialization not specifically associated with enabling the interrupts
used in lab.)

Write a program that computes the cost of painting and installing carpet in a
room. Assume that the room has one door, two windows, and one bookshelf. Your program must do the following:
a. Prompts the user to enter, in feet, the length, width, and height of a
room. Read the dimensions of the room.
b. Prompts the user to enter the widths and heights, in feet, of the door,
each window, and the bookshelf. Read these quantities.
c. Prompts the user to enter the cost, per square foot, of painting the
walls. Read these quantities.
d. Prompts the user to enter of cost, per square foot, of installing carpet.
Read these quantities.
